Polyacrylamide grafted Agar: Synthesis and applications of conventional and microwave assisted technique

► Polyacrylamide grafted Agar was synthesized by conventional technique and microwave assisted technique. ► Higher the percentage grafting of the graft copolymer, higher is its intrinsic viscosity. ► The graft copolymer proved superior flocculant in kaolin suspension and in waste water. ► The optimized flocculant dose as found in Kaolin suspension was 0.75 ppm.
