Due to increased industrialization, a lot of effluents containing toxic chemicals have been generated and low-cost treatment is needed for the removal of these heavy metal ions. One such is the Shrimp industry that has been commercialized for more than a century producing huge waste and these wastes are detrimental to the environment if not disposed of properly. This waste can be efficiently used in biosorption. This has been an interesting area in recent days due to its ease of operation and flexibility. The purpose of this review is to present the significant role of shrimp shells as effective biosorbents for the removal of noxious heavy metals from effluents. The literature review has been done on the thermodynamic characteristics of heavy metal (HM), adsorption behavior, equilibrium, and kinetics of the various industry effluents and their adsorption capacity.
