Abstract
Inventia se refera la chimie si anume la un procedeu de obtinere a rasinilor schimbatoare de ioni, modificate cu compusi de Bi(III), care pot fi utilizati in procesele de sorbtie si de separare a substantelor. Procedeul consta in aceea ca polimerii ionici reticulati care contin grupe puternic bazice, in prealabil se modifica cu compusi de Cr(III), apoi se trateaza cu solutie de 0,014...0,016 M Bi(NO3)3 cu pH 0,2 in raport de 1...2 g de polimer la 100 ml de solutie, la temperatura de 55...65?C timp de 5,0...5,5 ore. In aceste conditii bismutul este substituit complet de ionii de crom si polimerul obtinut poseda proprietati selective fata de anioni. ŕ
