Abstract
Studies on the sorption of rare-earth metals, uranium, and thorium from nitric acid solutions on different phosphor-containing solid extragents produced by the Russian ZAO Axion-RDM are performed. It is demonstrated that effective extraction of REM on phosphor-containing solid extragents is possible from solutions with HNO3 concentration up to 0.1 M and extraction of uranium and thorium from solutions of up to 6 M.
