Abstract
Invenţia se referă la chimie şi anume la un procedeu de purificare a soluţiilor de ionii de cianură, tiocianat şi cianat, inclusiv a apelor reziduale obţinute la extracţia metalelor neferoase şi preţioase şi din industria cocsochimică.Esenţa invenţiei constă în aceea că soluţia, care conţine ioni de cianură, tiocianat sau cianat se trece printr-o coloană cu sorbent schimbător de anioni selectiv, obţinut prin modificarea în prealabil a anioniţilor puternic bazici cu compuşi de fier(III), la tratarea a 0,5...1,0 g de anionit cu 100 ml de soluţie, ce conţine 6...8 g/l sulfat de fier(III) nonahidrat la temperatura de 45...55ºC timp de 8...12 ore.
