Abstract

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 0.01N-10N nitric acid and 0.01M-10M ammonium nitrate solutions. The distribution ratios of about 50 chemical elements from Na to Cm were determined by batch method using radioactive tracers. In the zirconium phosphate system, Cs shows the highest Kd value and most bivalent species are not adsorbed. A few elements are adsorbed on silica gel from acid solution. High Kd values are shown by Zr, Nb and Pa. In the charcoal system, most chemical elements are adsorbed to some extent except for alkali and alkaline earth ions.
