ABSTRACT. Biosorption is a cost effective tool for removing heavy metals from aqueous solutions. In the present study, M. azedarach biomass has been used for the biosorption of Ni(II) ion from aqueous solution. The effect of pH, contact time, concentration and temperature were separately studied. The optimum pH was found to be 6.0. 92% biosorption of Ni(II) ion was founded, when 25 mg/L of initial Ni(II) ion concentrations was used at room temperatures in 60 min. It was also observed that percent biosorption of Ni(II) increases with increase in temperature. The equilibrium biosorption data were analyzed by the Langmuir and Freundlich isotherms both were best fitted to our data. The maximum biosorption capacity (qmax) of 9.345 mg/g for Ni(II) according to Langmuir model. The kinetics of Ni(II) ion revealed that present biosorption process proceeds according to pseudo second order kinetics. From Thermodynamic parameters including Gibbs free energy change (∆G), enthalpy change (DH) and entropy change (ΔS), it was concluded that biosorption of Ni(II) ion using M. azedarach biomass is feasible, spontaneous and endothermic in nature.

“…The use of melia biomass is relatively recent and it was tested for As adsorption in a lab-scale study [13]. The proposed adsorbent was appropriate, suitable, and easily applicable in local areas because of its simplicity, easy operation and handling, and cost effectiveness, and can be used for arsenic removal from drinking water.…”

Contamination of water bodies such as rivers, lakes, aquifers, oceans, and groundwater has led to a serious problem of water pollution. The various reasons for this threat constitute both anthropogenic and non‐anthropogenic factors including population explosion, industrialization, and globalization, which lead to the addition of toxic metals, dyes, and organic and inorganic compounds in water. Consumption of these toxic metals for longer time may cause various disorders in the human body including decreased immunological defenses, disabilities associated with malnutrition, and high rate of upper gastrointestinal cancer. Remediation of water includes the elimination of contaminants for a pollution‐free environment. Attention has also been focused on developing green sustainable technologies that must be esthetic, eco‐friendly, socially acceptable, and economical. Water remediation using green technologies has been divided into two groups; bioremediation, that is decontamination using plants, fungi, algae, bacteria, and other microorganisms and second remediation method is through natural products or modified natural products. Bioremediation is the use of plants and microorganisms for the breakdown of contaminants to nontoxic or less harmful products. It is used to purify groundwater, soil, sludge‐carrying pesticides, hydrocarbons, and other organic chemicals for detoxification. Bioremediation consists of phytoremediation through which detoxification is carried out through green plants and their biomass. It helps in the removal of toxic metals by complexation. Periphyton biofilms composed of bacilli and cocci for the treatment of aquatic ecosystem remove COD, UV254 nm matter, and toxic metals; algal biomass is used for the removal of harmful dyes from wastewater. Natural products also emerge as potential compounds to remediate toxic metals from industrial effluents. Some of the natural products used for this purpose are polysaccharides, crab shell, papaya wood, etc.; modified natural products such as zeolites having selectivity for ammonia, transition metals, bacteria, and radioactive elements; functionalized silica gel for removing metals; nanomaterials as potential antimicrobial agents and to remove metals and organic contaminants; ionic liquids as excellent solvent for the extraction of various heavy metals; surfactant modification for removal of oxo ions such as chromate, oxalate, etc.; and inorganic–organic hybrid polymeric materials for water purification. The use of such materials will lead to a better and more sustainable way of treating polluted water.
