Abstract
Invenţia se referă la chimie şi anume la un procedeu de obţinere a răşinilor schimbătoare de ioni, modificate cu compuşi de Bi(III), care pot fi utilizaţi în procesele de sorbţie şi de separare a substanţelor.Procedeul constă în aceea că polimerii ionici reticulaţi care conţin grupe puternic bazice, în prealabil se modifică cu compuşi de Cr(III), apoi se tratează cu soluţie de 0,014…0,016 M Bi(NO3)3 cu pH 0,2 în raport de 1...2 g de polimer la 100 ml de soluţie, la temperatura de 55...65ºC timp de 5,0...5,5 ore.În aceste condiţii bismutul este substituit complet de ionii de crom şi polimerul obţinut posedă proprietăţi selective faţă de anioni.
