Abstract
Invenţia se referă la un procedeu de regenerare a anioniţilor puternic bazici modificaţi cu Cr(III) şi poate fi utilizată la regenerarea polimerilor ionici reticulaţi.Procedeul constă în aceea că anioniţii se tratează cu soluţie de 1,0...1,5 M H2SO4, timp de 1,0...1,5 ore, la temperatura de fierbere a băii marine.Rezultatul constă în aceea că polimerul epuizat, modificat cu compuşi de Cr (III), se regenerează pentru a fi modificat din nou sau utilizat în alte scopuri.
