Multi Heavy Metal Cyclic Adsorption-Desorption Characteristics of Commercial Resins and Chitosan Derivatives

Abstract

Considering the lacunae in the field of commercial resin and chitosan derivatives based multi-heavy metal sorptive removal from complex adsorbate systems, the PhD thesis involved the realization of five major objectives. These are as follows: (a) Efficacy of commercial resins (Amberlite IR 120H and Lewatit TP 260) for multi-heavy metal removal and resin regeneration from Cu and Zn dominant complex adsorbate systems. (b) Synthesis, characterization, batch adsorption and desorption studies of polyvinyl grafted chitosan variant derivatives (low CSPVA, medium CSPVA and high CSPVA) for multi-heavy metal removal and resin regeneration from Cu and Zn dominant complex adsorbate systems. (c) Synthesis, characterization, batch adsorption and desorption studies of citric acid grafted glutaraldehyde crosslinked chitosan variant derivatives (low Cit-CS, medium Cit-CS and high Cit-CS) for multi-heavy metal removal and resin regeneration from Cu and Zn dominant complex adsorbate systems. (d) Synthesis, characterization, batch adsorption and desorption studies of carboxymethyl grafted glutaraldehyde crosslinked chitosan variant derivatives (low CMCS, medium CMCS and high CMCS) for multi-heavy metal removal and resin regeneration from Cu and Zn dominant complex adsorbate systems. (e) Conceptual cost analysis for the multi-heavy metal ion removal from complex adsorbate systems.
