Over the past few years, activated carbon (AC) has attained significant attention as an efficient adsorbent for heavy metal (lead, cadmium, chromium etc.) removal. In Bangladesh, bagasse and jute fibre are the two most potential raw materials for producing activated carbon due to their high availability and low cost. The activated carbon was produced by thermal treatment method. The produced AC were characterized using FTIR, XRD, SEM etc. Batch experiments under agitation was also carried out for adsorption of heavy metals and then characterized using AAS (Atomic Adsorption Spectroscopy). Adsorption with commercially available activated carbon was also done to use as standard. Among all ACs produced in this study, the highest percentage removal of heavy metals which were Cr3+ and Cd2+ was at 57.06% and 43.01% respectively for J-400 ( AC produced from jute fibre at 4000C). This obtained value was 16.6% and 12.9% higher in comparison to Commercially available Activated carbon for Cr3+ and Cd2+ respectively.

This study investigated the potential of some agricultural wastes viz; African Star apple seed shell (ASS, plant source), crab shell (CS, animal source) and chicken egg shell (ES, animal source) as eco-friendly and low-cost biological materials for the removal of heavy metals from poultry wastewater. TS, TSS and TDS of the wastewater sample were assayed by filtration methods, chloride content by previously reported method and heavy metal contents (Zn, V, Cd, Fe, Ni, Cu, Co, Pb, Cr and Mn); were analyzed using Microwave Plasma Atomic Emission Spectrometer. The results of the solids and chloride contents of the poultry wastewater were TDS (3100 mg/L), TS (3700 mg/L), TSS (6000 mg/L) and chloride (4.7 g/L); all above the EPA permissible limits. Results of the FTIR analysis showed that ASS is an amide polymer while the CS and ES shells are mixtures of amide and carbonate polymers. Also, results of heavy metal analysis before and after adsorption showed that ASS caused removal of Zn, V, Fe, Cu, Co/ Pb and Mn by 48.27, 32.22, 49.64, 91.44, 100 and 82.39% respectively while Cd, Ni and Cr contents increased by 31, 61 and 48.3% respectively. CS showed removal of Fe, Ni/ Co/ Cr, Pb and Mn by 89.64, 100, 3.51 and 95.96% respectively while Zn, V, Cd and Cu contents increased by 1.7, 61.2, 76.1 and 68.1% respectively. Meanwhile, with ES, the contents of Zn, Fe, Ni, Cu, Cr and Mn increased by 31.56, 86.36, 100, 55.5, 45.80 and 90.33% respectively while the contents of V, Cd, Co and Pb decreased by 78.9, 86.7, 42.5 and 46.2% respectively. This study demonstrated the use of ASS, CS and ES as low- cost and eco-friendly agricultural wastes with significant potential for removal of heavy metals from wastewaters.

Removal Of Heavy Metals

Biosorption process is a promising technology for the removal of heavy metals from industrial wastes and effluents using low-cost and effective biosorbents. In the present study, adsorption of Pb2+, Cu2+, Fe2+, and Zn2+onto dried biomass of red seaweedKappaphycussp. was investigated as a function of pH, contact time, initial metal ion concentration, and temperature. The experimental data were evaluated by four isotherm models (Langmuir, Freundlich, Temkin, and Dubinin-Radushkevich) and four kinetic models (pseudo-first-order, pseudo-second-order, Elovich, and intraparticle diffusion models). The adsorption process was feasible, spontaneous, and endothermic in nature. Functional groups in the biomass involved in metal adsorption process were revealed as carboxylic and sulfonic acids and sulfonate by Fourier transform infrared analysis. A total of nine error functions were applied to validate the models. We strongly suggest the analysis of error functions for validating adsorption isotherm and kinetic models using linear methods. The present work shows that the red seaweedKappaphycussp. can be used as a potentially low-cost biosorbent for the removal of heavy metal ions from aqueous solutions. Further study is warranted to evaluate its feasibility for the removal of heavy metals from the real environment.

Discharge of heavy metals from metal processing industries is known to have adverse effects to the environment. Conventional treatment technologies for removal of heavy metals from aqueous solution are not economical and generate huge quantity of toxic chemical sludge. Biosorption of heavy metals by metabolically inactive non-living biomass of microbial or plant origin is an innovative and alternative technology for removal of these pollutants from aqueous solution. Therefore, in this study, it is aimed to investigate the potential of pandan leaves as a biosorbent to remove heavy metal, copper. The pandan leaves were extracted via solvent extraction method. The effect of dosage of biosorbent, pH aqueous solution, and the biosorption contact time towards removal of copper (Cu2+) ions were studied. The concentration of copper ions was analyzed by using atomic adsorption spectroscopy (AAS). The maximum biosorption of Cu2+ ions was obtained up to 70 % for 5ppm of initial copper ions loading by 1 hour.

Heavy metal wastewater poses a threat to human life and causes significant environmental problems. Bioremediation provides a sustainable waste management technique that uses organisms to remove heavy metals from contaminated water through a variety of different processes. Biosorption involves the use of biomass, such as plant extracts and microorganisms (bacteria, fungi, algae, yeast), and represents a low-cost and environmentally friendly method of bioremediation and resource management. Biosorption-based biosynthesis is proposed as a means of removing heavy metals from wastewaters and soils as it aids the development of heavy metal nanoparticles that may have an application within the technology industry. Phytomining provides a further green method of managing the metal content of wastewater. These approaches represent a viable means of removing toxic chemicals from the effluent produced during the process of manufacturing, and the bioremediation process, furthermore, has the potential to save metal resources from depletion. Biomimetic resource management comprises bioremediation, biosorption, biosynthesis, phytomining, and further methods that provide innovative ways of interpreting waste and pollutants as raw materials for research and industry, inspired by materials, structures, and processes in living nature.

Pollution of water bodies by heavy metals is an acute problem in Kazakhstan. Hence, search for and implementation of sustainable environmental technologies for water purification is of high priority. Activated carbon appears as an appropriate material as reflected in a number of previous studies. Due to a growing interest in low-cost active coals from renewable, rapidly recovering raw materials, especially for the purification of drinking water and wastewater, special attention has been in recent years been paid to the preparation activated carbons from some types of agricultural by-products. Along these lines a technology for producing new carbon-containing sorbents, i.e., activated carbon from Miscanthus straw (Мiscanthus × giganteus) is reported. The method of preparation, type of reactor, experimental conditions and the influence of the selected initial material on the properties of the resulting activated carbons are discussed. The activation of the primarily carbonized material in super-heated steam creates an activated coal material with a specific surface area of 541.9 m2/g and a specific pore volume of 0.232 cm3/g. The possible application for purification of water bodies from selected heavy metals was studied by estimation of the sorption capacity of the generated active coal material towards selected metal ions. The adsorption capacity for copper, zinc and lead ions is 90, 100, 500 mg/L, which allows to consider obtained by this method AC as an attractive alternative to traditional coal sorbents.
