“…Herein, the reactive solid phase means the part of the solid that is involved with the sorption. In a previous paper [12], it was found that the f d value of strontium (Sr) agreed with the K d value of Sr obtained from batch methods at the same liquid-phase stable Sr concentration, indicating that the K d of Sr can be evaluated by the f d of Sr.…”

A simple method of evaluating the distribution coefficient (K d ) of radioactive Ni was examined. The method is based on the measurement of the solid-liquid concentration distribution ratio ( f d ) of background stable Ni. To verify the method, the K d 's of both the radioactive Ni and stable Ni were simultaneously measured by using three different samples through batch sorption experiments in which radioactive Ni with a constant concentration and stable Ni with various concentrations coexisted. The f d of background stable Ni was then measured by extraction with 0.1 N CH 3 COONH 4 and 0.1 N HCl solutions to compare f d with K d . The results showed that the K d 's of radioactive Ni agreed with those of stable Ni, and that the f d corresponded to the K d when the liquid-phase concentration of stable Ni approached the background level. This indicates that the method of evaluating K d by using f d is applicable to Ni within the experiment.
