A sorption study of some metal ions on hydrogels based on Apple Pectin and Acrylamide

The apple processing units are likely to be expanded in Himachal Pradesh in future. The industrial by-product pomace a, renewable resource plays an important role in pectin manufacture. The objective of study is the extraction of pectin from apple pomace and to develop a new polymeric backbone. Conditions for optimum yield were evaluated as function of temperature, concentration of monomer, initiator, amount of water and reaction time for pectin with Acrylamide using KPS as initiator by chemical induced method. These hydro gels were used in sorption of Cu2+, Fe2+ and Co2+ metal ions. These results of ion sorption are reflected in high uptake value for Co2+ and Fe2+.
