Preparation and Characterization of Cotton Textile Graft Copolymers as Cation Exchanger

Kh. M. Mostafa

Acrylic Acid (AA) was graft copolymerized with cotton cellulose in fabric form to prepare poly (AA)-cotton graft copolymer cation exchanger using Fe2+/BrO3¯ redox system in aqueous medium under a nitrogen atmosphere. The effect of Fe2+, BrO3¯ and monomer concentrations, pH as well as time and temperature of polymerization were studied by determining the grafting parameters gravimetrically, like Graft Yield (GY %) and Graft Reaction Efficiency (GRE %). On the other hand, the newly prepared poly (AA)-cotton graft copolymers were characterized for different heavy metals ions removal to determined their suitability as cation exchanger. On the basis of a detailed investigation of the above factors, the appropriate conditions for grafting were as follows: Fe2+, 0.005 mol L-1; BrO3¯, 0.001 mol L-1; pH, 2; monomer, (50% based on weight of substrate); time, 90 min and temperature, 35°C. On the other hand, the potential value of the newly prepared poly (AA)-cotton graft copolymer to serve as cation exchanger was assessed through measurements of critical properties such as removal of different heavy metal ions from their solutions as well as durability.
