In this study, the possibilities of selective sorption neodymium and praseodymium ions from a mixture their solution using interpolymer systems composed two industrial sorbents, cation exchangers KU-2-8 (Na+) AB-17-8 (Cl-), at different molar ratios were investigated. The processes desorption carried out in modes: dynamic (with active stirring) static (without stirring working which REEs extracted). According to obtained results, mode 4:2 3:3 does not lead any selectivity. However, high degree extraction was noted for both ions: Pr3+ = 99.36%, Nd3+ 95.67% system 81.33%, 79% system. mode, metals significantly lower: 19.33%, 24%, but greater selectivity with respect observed. With ratio 4:2, sorbed better than by 24.16%, 39.83%. When cationite nitric acid, similar tendency preserved. Thus, it shown that can be used industry varying conditions successful solutions.
