Abstract
Invenţia se referă la procedeul de obţinere a răşinilor schimbătoare de ioni, modificate cu compuşi metalici şi poate fi utilizată în procesele de sorbţie şi separare a substanţelor, în cataliză.Procedeul constă în aceea că polimerii se tratează cu o soluţie de alauni de crom sau de sulfat de Cr(III) ce conţine 2,0…2,5 g/L de Cr(III), cu pH 4…4,3, în raport de 0,2…1,0 g de polimer/100 mL de soluţie, la temperatura de 55…65°C, timp de 18…20 ore. Efectuarea procedeului în aceste condiţii permite obţinerea anioniţilor modificaţi cu Cr(III) având un conţinut sporit de metal în faza polimeră.Rezultatul tehnic constă în modificarea specifică a polimerilor, care astfel devin selectivi în sorbţia ionilor NCS-, NCO-, CN- şi alţii.
