Abstract
Three Iranian natural zeolites were characterized and evaluated for their abilities to take up Ba+2, Ca+2, K+ and Na+ from radioactive waste waters. The distribution coefficient values (K d ) of the cations were measured and investigated as a function of pH. Four different cationic forms (Na, K, NH4, and Ca) were also prepared and theirK d values were determined. Some cations such as potassium presented highK d values both in natural and exchanged zeolites. In sodium and ammonium exchanged forms theK d values increased between 7 to 100 times with respect to the untreated zeolite.
