Abstract
In the present study, an attempt has been made to synthesize a novel hydrogel from apple pectin extracted from Apple pomaces (waste). The hydrogel was synthesized by grafting Acrylamide (AAm) onto Apple pectin using Potassium peroxydisulphate as a free radical initiator in a redox system comprising Potassium peroxydisulphate Sulfuric acid (KPS SA). The optimum reaction condition for grafting acrylamide monomer onto pectin was evaluated by varying the concentration of initiator, monomer, sulfuric acid, water, temperature and reaction time. The graft copolymerization conditions were systematically optimized to achieve a hydrogel with the highest yield percent. The biodegradability of pectin-g-AAm grafted polymer in comparison with backbone polymer was also evaluated. Removing heavy metal ions by hydrogels provides an environmentally friendly, low-cost, and effective technique than the precipitation process or ion exchangers. The Sorption behaviour of the Cu+2, Fe+2 and Co+2 ions by the apple pectin and the apple pectin grafted AAm Hydrogel on different grafting percent as a function of time were studied at a constant temperature. The salt sensitivity and cation exchange property of pectin g AAm polymer hydrogels marks their suitability for use in water purification and drugs.
