In the present study, the efficiency of Annona senegalensis fiber to remove crude oil from aqueous solution was evaluated. The crude Annona senegalensis (CAS), retted Annona senegalensis (RAS) and bleach Annona senegalensis (PFAS) were subjected to sorption studies to optimize their sorption capacity. The results revealed that the efficiency of sorbent to remove crude oil from water is related to the sorbent weight, contact time, initial oil concentration and temperature of sorption. It was found out that increase in sorbent weight led to increase in sorption capacity from 3.99-5.25g/g, 5.51-7.12g/g, and 5.01-6.72g/g in CAS, RAS and PFAS respectively. Increased in Initial oil concentration also increased the oil sorption capacity by 20-21% until it reach equilibrium. Sorption time was varied from 10, 20, 30, 40, 50, 60 and 70 minutes and the highest sorption capacity was recorded at 30 minutes before a gradual decreased was observed. Sorption capacity decreased with increased in temperature above 400C. The sorbent exhibited good reusability after 8 cycles, with less than 50 % reduction in sorption capacity. The kinetics of crude oil sorption onto CAS, RAS and PFAS follow the second- order model with correlation coefficients higher than 0.99. The results obtained revealed that crude oil adsorption onto the Annona senegalensis fiber can be used as an effective adsorbent to oil spill cleanup in water bodies.

This study will present a novel method for crude oil remediation in water. The research was carried out to explore the possible application of Sterculia setigera as a potential biodegradable sorbent for oil cleanup from water. The crude Sterculia setigera (CSS), retted Sterculia setigera (RSS) and bleached Sterculia setigera (PFSS) were subjected to sorption studies to optimize their sorption capacity. The results revealed that the efficiency of sorbent to remove crude oil from water is related to the sorbent weight, contact time, initial oil concentration and temperature of sorption. It was found that increase in sorbent weight led to increase in sorption capacity from 3.75 -5.12 g/g, 4.72- 6.41 g/g, and 4.61-6.18 g/g in CSS, RSS and PFSS respectively. Oil sorption capacity increases by 21-27% when oil concentration was varied from 5-20 g. Contact time played a role only at the beginning of oil sorption study and became less important near equilibrium. Sorption time was varied from 10-70 min and the highest sorption capacity was recorded at 30 min. then it gradually reduced and became steady. The effect of temperature was investigated from 30-60°C. A decreased of 34-37% in oil sorption capacity was observed with increased in temperature.  RSS exhibit lower water sorption when compared to the other sorbents. The sorbents showed good reusability after 8 cycles, with less than 50% reduction in sorption capacity and good reusability. Sterculia setigera demonstrated good potentials for utilization as natural sorbent for oil cleanup.

Biosorbents have been highlighted as an alternative method for the removal of contaminants from spills or leaks of oil and its derivatives, since they are biodegradable, are highly available, low-cost, and have a good sorption capacity. This research investigated the sorption capacity of Calotropis procera fiber in natura (CP) and thermally treated (150 °C and 200 °C) for crude oil removal and recovery. The oil sorption tests were carried out in a dry and water (layer) static systems. The assays revealed that CP fiber has excellent hydrophobic-oil properties and good crude oil sorption capacity, about 75 times its own weight (76.32 g/g). The results of the treated fibers, CPT150 and CPT200, showed oil sorption capacities (in 24 h) higher than CP, between 94.31–103.37 g/g and 124.60–180.95 g/g, respectively. The results from sample CPT200 showed that it can be an excellent biosorbent for the removal of crude oil and other derivatives due to its high hydrophobicity, great reuse/resorption capacity, and ability to retain oil within the fiber lumens. Thus, it can be applied in the recovery, cleaning, and removal of petroleum products and its derivatives from spills and leaks in the future.

AbstractThe problem of oil spill pollution associated with the transport of crude oil and its products across the globe is of serious concern. The sorption technique has proved to be promising for oil spill treatment but is limited by the hydrophilic nature of most natural organic sorbents. The combo of natural organic and inorganic sorbents have been found to enhance the hydrophobicity for oil sorption. Therefore this study was aimed at the preparation of a novel feldspar-banana peel biochar composite (FBPC) with enhanced hydrophobicity for the sorption of crude oil. The prepared sorbent was characterised by the scanning electron microscopy (SEM) and X-ray diffraction (XRD) techniques, while the crude oil was characterised using standard methods. Batch sorption was used to determine the effect of contact time (30–150 min), temperature (25–100 °C), pH (2.0–10.0), oil concentration (4.0–12.0 g/L) and sorbent dosage (0.1–0.5 g) on sorption. SEM analysis of FBPC revealed a porous structure, while XRD confirmed the crystalline phases of feldspar. The crude oil samples had pH (6.40–6.60), density (0.960 0 0.962 g/cm3), kinematic viscosity (24.0–27.6 cSt) and API gravity (24.25–24.51°). The Langmuir model with R2 > 0.7781 presented the best fit than the Temkin and Freundlich model in the isotherm analysis, while the pseudo-second-order model with R2 > 0.9711 was applicable in the kinetics of sorption. The thermodynamic analysis revealed a decrease in randomness at the crude oil-FBPC interface. The prepared FBPC was found to be an efficient inorganic–organic composite sorbent with enhanced hydrophobicity for the sorption of crude oil.

The marine environment is constantly at risk of pollution by hydrocarbon spills that requires its cleanup to protect the environment and human health. Posidonia oceanica (L.) (PO) beach balls, which are characteristic of the Mediterranean Sea and abundant on the beaches, are used as biosorbent to remove hydrocarbons from the sea. The impact of several factors such as oil concentration, time sorption, and weight sorbent was investigated to determine the oil and water sorption capacity for raw and milled P. oceanica fibers. The study of kinetic models for initial crude oil concentration of 2.5, 5, 8.8, 10, 15, 20, 30, and 40 g/L revealed that crude uptake followed the pseudo-first-order model while, for isotherm models, the crude uptake onto the P. oceanica tended to fit the Langmuir model. Experiments were performed according to two systems: a pure oil and pure water system and a mixed oil/water system. For the dry system (pure oil and pure water), the maximum oil and water sorption capacity of raw and milled fibers was found to be 5.5 g/g and 14 g/g for oil and 14.95 g/g and 15.84 g/g for water, respectively, whereas, in the mixed oil/water system, the maximum oil and water sorption capacity was estimated as 4.74 g/g, 12.80 g/g and 7.41 g/g, 8.31 g/g, respectively. The results showed that, in spite of their absorbency of a lot of water, the milled fibers with grain size ranging between 0.5 mm and 1 mm might be the relevant sorbent for the elimination of crude oil from seawater thanks to its efficient sorption capacity and low cost.

AbstractExiguobacterium sp. AO-11 was immobilized on bio-cord at 109 CFU g−1 carrier for the removal of crude oil from marine environments. To prepare a ready-to-use bioremediation product, the shelf life of the immobilized cells was calculated. Approximately 90% of 0.25% (v/v) crude oil removal was achieved within 9 days when the starved state of immobilized cells was used. The oil removal activity of the immobilized cells was maintained in the presence of oil dispersant (89%) and at pH values of 7–9. Meanwhile, pH, oil concentration and salinity affected the oil removal efficacy. The immobilized cells could be reused for at least 5 cycles. The Arrhenius equation describing the relationship between the rate of reaction and temperature was validated as a useful model of the kinetics of retention of activity by an immobilized biocatalyst. It was estimated that the immobilized cells could be stored in a non-vacuum bag containing phosphate buffer (pH 7.0) at 30 °C for 39 days to retain the cells at 107 CFU g−1 carrier and more than 50% degradation activity. These results indicated the potential of using bio-cord-immobilized crude oil-degrading Exiguobacterium sp. AO-11 as a bioremediation product in a marine environment.

PP fibers are commonly used for oil spill cleanup. In order to improve the oil-sorption capacity of the PP fibers, the blended PP fiber of various MFR and unblended PP fiber of certain MFR were fabricated as sorbents by a swirl die melt-blowing device in this study. The material properties of the PP fibers were examined by scanning electron microscopy and contact-angle measurement. The oil sorption and sorption-desorption tests show that the blended PP fibers have a much higher oil-sorption capacity than the unblended PP fibers and an excellent reusability.

<div><p><em>In this paper jute fibre was modified with three different chemical modification techniques namely acetylation using acetic anhydride, grafting using butyl acrylate monomer and fatty acid modification using oleic acid to increase the oil sorption capacity of the fibre. All the above modifications were carried out in fibrous as well as nonwoven form to study the effect of substrate geometry on oil sorption capacity. It was found that oil sorption capacity of the chemically modified jute fibres was higher than that of the raw fibres and in case of the chemically modified nonwoven it was much higher than the raw as well as modified loose fibres. Reusability of the modified substrates was also tested and it was found that all the substrates could be squeezed to recover oil and reused at least three times. </em><em>Nonwoven fabric’s substrate geometry permits easy rolling-in and rolling-out of the fabric for the recovery of the oil from the surface of the water. </em><em>Also these oil sorption-active materials being biodegradable can be used to substitute non-biodegradable synthetic materials in oil spill cleanup.</em></p></div>

Oil Spill Cleanup

Purpose In recent years, oil spill pollution has become one of the main problems of environmental pollution. Recovering oil by means of sorbent materials is a very promising approach and has acquired more attention due to its high cleanup efficiency. Compared to synthetic fibrous sorbents, the use of natural fibers in oil spill cleanups offers several advantages including environmental friendliness, degradable features and cost-effectiveness. Therefore, studies on developing sorbents using natural fibers for oil spill cleanup applications have become a research hotspot. Design/methodology/approach This paper reviews the work conducted by several researchers in developing oil sorbents from fibers such as cattail, nettle, cotton, milkweed, kapok, populous seed fiber and Metaplexis japonica fiber. Some featured critical parameters influencing the oil sorption capacity of fibrous substrates are discussed. Oil sorption capacity and reusability performance of various fibers are also discussed. Recent developments in oil spill cleanups and test methods for oil sorbents are briefly covered. Findings The main parameters influencing the oil sorption capacity of sorbents are fiber morphological structure, fiber density (g/cc), wax (%), hollowness (%) and water contact angle. An extensive literature review showed that oil sorption capacity is highest for Metaplexis japonica fiber followed by populous seed fiber, kapok, milkweed, cotton, nettle and cattail fiber. After use, the sorbents can be buried under soil or they can also be burned so that they can be vanished from the surface without causing environmental-related issues. Originality/value This review paper aims to summarize research studies conducted related to various natural fibers for oil spill cleanups, fiber structural characteristics influencing oil sorption and recent developments in oil spill cleanups. This work will inspire future researchers with various knowledge backgrounds, particularly, from a sustainability perspective.

Sorbents were produced on the basis of rice husk, rubber crump and apricot stone by carbonization. They all possessed a high sorption capacity for oil and oil products. With the use of these sorbents an oil overflow was experimentally removed from the surface of the river Syrdarya (Kyzylorda). Results showed that the oil sorption capacities of carbonized rice husk, rubber crumb and apricot stone were 18, 14 and 7 g/g, respectively. The material obtained by carbonization of rice husk has very good buoyancy characteristics, high oil sorption capacity and high hydrophobicity. The effects of contact time, water temperature, amount and type of sorbents on the oil sorption capacity of the carbonized sorbents were further studied on the basis of microstructure and morphology using optical digital microscopy and scanning electron microscopy (SEM). The results of the SEM and optical microscopy studies strongly indicate that carbonization is a suitable method for improving the porous structure of the sorbents particles compared to the virgin samples. This research provides the basis for the development of a new environmental material with optimal characteristics, providing efficient sorption of oil and oil products from an aqueous medium.

Oil spills generally cause worldwide concern due to their detrimental effects on the environment and the economy. An assortment of commercial systems has been developed to control these spills, including the use of agricultural wastes as sorbents. This work deals with raw and modified mangrove barks (Rhizophora apiculata), an industrial lignocellulosic waste, as a low cost adsorbent for oil-product-spill cleanup in the aquatic environment. Mangrove bark was modified using fatty acids (oleic acid and palmitic acid) to improve its adsorption capacity. The oil sorption capacity of the modified bark was studied and compared with that of the raw bark. Kinetic tests were conducted with a series of contact times. The influence of particle size, oil dosage, pH and temperature on oil sorption capacity was investigated. The results showed that oleic acid treated bark has a higher sorption capacity (2,860.00 ± 2.00 mg/g) than untreated bark for Tapis crude oil. A correlation between surface functional groups, morphology and surface area of the adsorbent was studied by Fourier transform infrared spectrum, field emission scanning electron microscopy images and Brunauer–Emmett–Teller analysis. Isotherm study was conducted using the Langmuir and Freundlich isotherm models. The result showed that adsorption of crude oil on treated mangrove bark could be best described by the Langmuir model.
