Abstract
We theoretically considered the distribution of 60Co and 85Sr to ion exchangers from solution that contained Ca++ and Mg++ simultaneously as major cations, and derived a equation that expresses the quantity of 60Co or 85Sr adsorbed to an ion exchanger under the influence of these two major cations. Then we performed column experiments to determine Kd values of these two radionuclides in solutions containing Ca++ and Mg++ simultaneously to three ion exchangers, Amberlite IR-120B, Green sand and KUR sand. Experimental results of this study certifies that the equation is applicable to estimate the influence of Ca++ and Mg++ on adsorption of tracer 60Co or 85Sr.
