Abstract:

Summary: Poly(styrene) was synthesized by suspension polymerization of styrene. Molar mass of poly(styrene) was determined by viscosity method. Sulfonated poly(styrene) was synthesized by direct sulfonation of poly(styrene) at 40oC. These products were identified by using IR spectroscopic technique. Cation exchange properties of sulfonated poly(styrene) have been determined for some metal ions such as Ni2+; Zn2+; Cu2+ and Ca2+. The distribution co-efficient and apparent adsorption capacities show that selectivity order of the metals as follow: Ni2+ > Zn2+ > Cu2+ > Ca2+. It was found that by increasing the pH of solution; the distribution Co-effecients (Kd) value also increased.
