Cesium sorption behavior of a mordenite type synthetic zeolite and its modified form obtained by acid treatment

A locally produced mordenite type synthetic zeolite and its modified form o btained by the treatment with dilute hydrochloric acid were tested for thei r cesium uptake characteristics. The two zeolites were compared with other commercially available synthetic zeolites with respect to their ability to sorb radiocesium from dilute nitric acid solution. The effects of the chang es in the composition of the solution including the concentration of nitric acid, sodium and cesium on the uptake of cesium were investigated. The res ults can be used in the removing processor radiocesium from different types of nuclear plant effluents by these zeolites.
