Summary:Alum and other inorganic coagulants have been in use for water treatment since time immemorial. However, exposure to the consecutive metal ions results in chronic effects, the well known of which is Alzheimer’s disease. Alternatives to these coagulants are biopolymer based graft copolymer as flocculant. They are required in minute dosage, non-toxic and are eco-friendly. In this study, alginic acid based graft copolymers have been synthesized via conventional and microwave based technique. Molecular characterization of synthesized graft copolymers have been carried out via standard physicochemical techniques. A comparative investigation of flocculation performance of alginic acid derivatives [synthesized by both the methods i.e., Alg-g-PAM(C) and Alg-g-PAM(M)] and coagulation efficacy of alum has been accomplished in various model suspensions via standard jar test procedure. As anticipated, the flocculation efficacy of Alg-g-PAM(M) has been found much higher than that of Alg-g-PAM(C). Further, the synthesized derivatives exhibited excellent capability in reduction of pollutant load including toxic metal ions removal from wastewater.
