Abstract
Invenţia se referă la un procedeu de obţinere a răşinilor schimbătoare de ioni, modificate cu compuşi metalici şi poate fi utilizată în procesele de sorbţie, separare a substanţelor şi în cataliză.Procedeul constă în aceea că polimerii se tratează cu o soluţie de alauni sau sulfat de aluminiu ce conţine 13,0...17,0 g/L Al(III) cu pH 3,4...3,5, în raport de 0,2...0,5 g de polimer/100 mL de soluţie, la temperatura de 80...90°C, timp de 16...18 ore.
