Cleaning of Wastewater from Total Coliform Using Chitosan–Grafted–Poly(2-methylaniline)

The preparation and characterization of a low-cost solid materials chitosan–graft–poly(2-methylaniline) as anti-coliform present in wastewater are confirmed by FTIR, TGA, XRD and SEM. The preparation is performed using ammonium persulphate as an oxidant. The data reveals that the grafting process enhances the efficiency of both chitosan and homo-poly(2-methylaniline) to remove coliform present in wastewater. The used wastewater contains 1600 colonies on testing total coliform using classical membrane filter techniques. The total coliform present in wastewater becomes zero by using 50 ppm of the graft, 100 ppm of chitosan and 1000 ppm of poly(2-methylaniline).
