چکیده
|
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 40°c. 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.
