Abstract

Invenţia se referă la un procedeu de regenerare a anioniţilor puternic bazici modificaţi cu Fe (III) şi poate fi utilizată la regenerarea polimerilor ionici reticulaţi.Procedeul constă în aceea că anioniţii se tratează cu soluţie de 0,5...1,5 M HCl, timp de 1,5...2,5 ore, la temperatura camerei.Rezultatul constă în aceea că polimerul epuizat, modificat cu compuşi de Fe (III) la utilizarea lui în diferite procese tehnologice, se regenerează pentru a fi din nou modificat sau utilizat în alte scopuri.
