Abstract

The elution behavior of Sr sorbed on zeolite columns was investigated in connection with the distribution coefficient Kd between desired zeolites and aqueous solutions. The Kd values decreased with increasing concentrations of coexisting inorganic cations and EDTA. The retention volume VR on zeolite column was predicted from the Kd value. An EDTA solution was desirable for the quantitative elution of sorbed Sr from the column owing to the low Kd value reduced by complex formation with EDTA. The column efficiency and the elution percentage were improved with increasing temperature and decreasing flow rate. The structure of zeolite A remained unaltered after the repetitive use as the column packing.
