Adsorption of Sr and Cs by Clay From Different Area

Distribution coefficients of 18 clays to ⁹⁰Sr and¹³⁷Cs were determined and the adsorption capability of different material was compared. The results show that zeolite from Zhejiang has an adsorption ratio of 2 112.0 mL/g to Sr which is top in all samples, adsorption ratio of zeolite from Chifeng, Inner Mongolia to Cs is 3 495.0 mL/g, top of all samples. Adsorption ratio of clay samples from different area have great diversity. Adsorption ratio to Sr has a distribution from 22.4 to 2 112.0 mL/g. Adsorption ratio to Cs has a distribution from 43.5 to 3 495.0 mL/g. Adsorption of most samples to Cs are more than that to Sr, and the adsorption capability of same samples to Sr is same to that to Cs.
