The extraction of yttrium ions by interpolymer systems based on industrial ionites: KU 2-8 cationite and AB-17 anionite was studied. The dependences of the yttrium content in the aqueous medium after sorption by the interpolymer system were studied KU 2-8:AB17-8 depending on the time, the degree of binding of the polymer chain (with respect to yttrium ions) by the initial ionites and interpolymer systems KU 2-8: AB-17-8. The maximum content of yttrium ions in the aqueous medium after sorption is observed at ratios of 3:3 and 4: 2 and the duration of remote interaction is 88 hours. At the same time, the content of yttrium in the aqueous medium after sorption is 60 mol.% and 56.4 mol.%, respectively. High values of the degree of binding of the polymer chain with respect to yttrium are observed at the ratios KU 2-8: AB-17-8=3:3
