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.

Ships, seeps from the seabed, municipal and industrial waste waters, and the atmosphere are the main sources of sea water contamination with oil and oil products. During the satellite monitoring of the Kravtsovskoe oilfield (D-6) (2004-2015) the area west of Sambia Peninsula and anchorage in front of entrance to Kaliningrad Sea Canal were localized as the most polluted area of the Southeastern Baltic Sea. Oil spill drift forecast from these areas with a help of Seatrack Web model (SMHI, HELCOM) has shown that the average annual direction of oil pollution drift is directed to the North-East. In some cases, leakage of oil or oil products from ships west of Sambia Peninsula could be a reason of oil contamination of beaches of the “Curonian Spit” National Park.

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.

Research results of influence of volume mass of crosslinked and foamed sorbents on the basis of secondary high-impact polystyrene with bitumen and zinc stearate upon their sorption capacity are represented. The mechano-chemical synthesis of foamed polymeric sorbents was carried out on the extruder with a three zone material cylinder. Azodicarbonamide was used as foaming agent and dicumyl peroxide was used as crosslinking agent. Foam polymer sorbents have a high buoyancy and hydrophobicity. This circumstance contributes to increasing the selectivity of sorption process of oil and oil products from water surface. The sorption capacity was determined by gravimetric method according to difference between sorbent weights before and after sorption. It was shown that petroleum are better sorbed on foamed polymeric sorbents with low volume weight and greater diameter of closed-celled structures. In the same time the diesel fuel sorbed well on sorbents with relatively high volume weight and accordingly lesser diameter of pores and cells. Petroleum oils are most effectively sorbed on foamed polymeric sorbents which volume weight and cells diameter are interim in comparison with sorbents for sorption of petroleum and diesel fuel. It was determined that rate of sorption processes increases with rising of temperature of aqueous medium independently on pores and cells diameter. In this case changing in sorption capacity occurs according to certain regularity depending on sorbate type, volume weight of sorbent and medium temperature. It was shown that obtained sorbents are characterized by capability to multiple regeneration at keeping of high buoyancy, hydrophobicity and sorption capacity on petroleum and oil products.

Objectives. This study aims to establish the available porosity of a sorbent based on carbonized rice husk and investigate its sorption properties for oil and oil products.Methods. A rice-husk-based sorbent carbonized at 400°С for 30 min was selected as the subject. The porosity of this sorbent is analyzed with the help of mercury porosimeters, the Pascal 140 EVO and Pascal 240 EVO. The sorption properties of the sorbent are also studied when cleaning water containing oil and oil products.Results. The test sample is a bulk porous material with a pore volume of 0.015 cm/g; porosity higher than 15% was found, and the pore size distribution is shown. Studies were conducted on the sorption of oil and oil products as well as the possibility of using the aforementioned sorbent as a filtering material in the purification of water containing oil products. We investigated the sorption processes under dynamic and static conditions. The methodology for measuring the porous structure of solid materials on the mercury porosimeter, Pascal 140 EVO, was examined. The texture characteristics of the sorbent’s porous structure were determined, which is primarily the total volume of pores, the values of the specific surface area, and the volume of the microspores and mesopores.Conclusions. The materials studied can be used as sorbents with a developed porous structure for purification of water with dissolved and emulsified petroleum products.

<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.
