Copolymer was synthesized by condensation of p-Cresol (p-C) and Adipamide (A) with Formaldehyde (F) in the presence of 2M HCl as catalyst with 4:1:5 molar ratios of reacting monomers. Water is the most important constituent of our body. Thus, its quality should be good and perfect because it directly affects our health. Water pollution due to arsenic leaching is one of the biggest problems all over the world. Ion-exchange studies of this purified copolymer resin were carried out for As3 ions. ‘A’ proved to be a selective chelating ion-exchange copolymer for certain metals. Chelating ionexchange properties of this copolymer were studied for As3 ions. Batch equilibrium method was employed to study the selectivity of metal ion uptake involving the measurements of the distribution of a given metal ion between the polymer sample and a solution containing the metal ion. The study was carried out over a wide pH range and in media of various ionic strengths. The copolymer showed a higher selectivity for As3 ions.
