• Adsorption behavior of inorganic ions were systematically surveyed through radiochemical methods. Adsorbents used were zirconium phosphate, silica gel and charcoal, and the aqueous phases were 0.01<SUB>N</SUB>-10<SUB>N</SUB> nitric acid and 0.01<SUB>M</SUB>-10<SUB>M</SUB> ammonium nitrate solutions. The distribution ratios of about 50 chemical elements from Na to Cm were determined by batch method using radioactive tracers.<BR>In the zirconium phosphate system, Cs shows the highest Kd value and most bivalent species are not adsorbed.<BR> A few elements are adsorbed on silica gel from acid solution. High Kd values are shown by Zr, Nb and Pa.<BR> In the charcoal system, most chemical elements are adsorbed to some extent except for alkali and alkaline earth ions.
