Treatment of Textile Wastewater using Chitosan and Chitosan Grafted Acrylamide by Microwave Synthesis

Polymeric flocculants based on single chitosan and polyacrylamide grafted chitosan (ch-g-pam) have been successfully synthesized via microwave initiated method. under optimal grafting conditions, 30.4% grafting has been observed in case of the microwave irradiation with exposed time, 76s and power, 640mw (80% from full power). the synthesized graft copolymers have been characterized by ftir spectroscopy. acidic medium was the best condition for flocculation with optimum ph of 3 and 4 using ch-g-pam and chitosan, respectively. the longer the settling time, the better the flocculation performance as long as the flocs did not break. 60-90 minutes was the best settling time with optimum dosage of 0.1 g for both flocculants. grafted chitosan with pam showed the best result in removing the contaminants compared to single chitosan.
