Анализ процессов соосаждения радионуклидов стронция и тория с гидроксидами железа и циркония

Abstract

In this work, the results of the research of thorium coprecipitation of with iron hydroxide and strontium coprecipitation with iron and zirconium hydroxides are presented. Influence of the major factors on coprecipitation is investigated, speciation of the components is calculated, solubility curves, dependences of extraction degree on рН and concentration of the solution are constructed. Based on the received results, possible mechanisms are defined and conditions of thorium and strontium coprecipitation are analyzed.
