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 O.OlN-lON nitric acid and O.OlM-lOM ammonium nitrate solutions. The distribution ratios of about 50 chemical elements from Na to Cm were determined by hatch 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.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
