Grafted copolymer of Plantago psyllium mucilage and acrylonitrile has been synthesized in the presence of nitrogen using ceric ion-nitric acid redox system. P. psyllium-grafted-polyacrylonitrile (PSY-g-PAN) was characterized by IR spectroscopy and tested for its flocculation efficiency in textile effluent by the standard jar test method. The effects of polymer dose, pH and contact time on the removal of solid waste from textile effluent is reported. The optimum dose was found to be 1.6 mg/L, at which a maximum solid removal of 94% suspended solid (SS) and 80% total dissolved solid (TDS) was seen. The most suitable pH was acidic (pH 4.0) and neutral (pH 7.0), for SS and TDS removal, respectively. The optimum treatment duration was 1 hour. X-ray analysis of PSY-gPAN and solid waste from effluent before and after treatment suggests the interaction of the solid waste with the PSY-g-PAN copolymer.
