Polymethacrylic acid grafted psyllium (Psy-g-PMA): a novel material for waste water treatment

Polymethacrylic acid grafted psyllium (Psy- g -PMA) was synthesized by microwave assisted method, which involves a microwave irradiation in synergism with silver sulfate as a free radical initiator to initiate grafting reaction. Psy- g -PMA grades have been synthesized and characterized on structura...

description Polymethacrylic acid grafted psyllium (Psy- g -PMA) was synthesized by microwave assisted method, which involves a microwave irradiation in synergism with silver sulfate as a free radical initiator to initiate grafting reaction. Psy- g -PMA grades have been synthesized and characterized on structural basis (elemental analysis, FTIR spectroscopy, intrinsic viscosity study) as well as morphological and thermal studies, taking psyllium as reference. The effects of reaction time, amount of monomer and silver sulfate (free radical initiator) on grafting of PMA on psyllium backbone have been studied. It is observed that all the grades of Psy- g -PMA have higher intrinsic viscosities than that of psyllium. The best synthesized grade was Psy- g -PMA having intrinsic viscosity of 6.93 and 58 % grafting of PMA on the main polymer backbone. Further Psy- g -PMA applications as flocculants for waste water treatment have been investigated. Psy- g -PMA resulted in higher decrease in the flocculation parameters such as total dissolved solid or total solids compared to psyllium. Hence the result shows the possible application of grafted psyllium in wastewater treatment.
