“…Biosorption of zinc on these non-living biosorbents give certain advantages such as Harser reaction environment can be employed, sudden death of biomass population can be avoided, and regeneration and reuse of the biosorbent is possible. However, there is 3 Physico-chemical methods for heavy metal removal from wastewater Various physico-chemical techniques used for the removal of zinc include coagulation-flocculation, chemical precipitation, membrane filtration, flotation, ion exchange, reverse osmosis, liquid extraction, activated carbon adsorption, and electrochemical treatment techniques [7,26]. In general, physico-chemical treatments offer various advantages such as their rapid process, ease of operation, and control, flexibility to change of temperature.…”

Zinc remediation of aqueous streams is of special concern due to its highly toxic and persistent nature. Conventional treatment technologies for the removal of zinc are not economical and further generate huge quantity of toxic chemical sludge. Biosorption is emerging as a potential alternative to the existing conventional technologies for the removal of metal ions from aqueous solutions. Mechanisms involved in the biosorption process include chemisorption, complexation, adsorption-complexation on surface and pores, ion exchange, microprecipitation, heavy metal hydroxide condensation onto the bio surface, and surface adsorption. Biosorption largely depends on parameters such as pH, the initial metal ion concentration, biomass concentration, presence of various competitive metal ions in solution, and to a limited extent on temperature. Biosorption using biomass such as agricultural wastes, industrial residues, municipal solid waste, biosolids, food processing waste, aquatic plants, animal wastes, etc., is regarded as a cost-effective technique for the treatment of high volume and low concentration complex wastewaters containing zinc metal. Very few reviews are available where readers can get an overview of the sorption capacities of agro based biomasses used for zinc remediation together with the traditional remediation methods. The purpose of this review article is to provide the scattered available information on various aspects of utilization of the agro based biomasses for zinc metal ions removal. An extensive table summarizes the sorption capacities of various adsorbents. These biosorbents can be modified using various methods for better efficiency and multiple reuses to enhance their applicability at industrial scale. We have incorporated most of the valuable available literature on zinc removal from waste water using agro based biomasses in this review.
