Abstract

Inventia se refera la un procedeu de regenerare a ionitului cu continut de nichel si zinc. Procedeul, conform inventiei, include vacuumarea ionitului pana la presiunea remanenta de 0,1…0,3 kg/cm2 in decurs de 5…10 min si tratarea ulterioara a acestuia la vacuumare cu o solutie de eluant care contine, in g/L:clorura de amoniu 80...100acid boric 8…10apa restul.Rezultatul consta in majorarea gradului de regenerare a ionitului.The invention relates to a process for regenerating ionite with nickel and zinc content. The process, according to the invention, includes vacuuming the ionite up to the remaining pressure of 0.1… 0.3 kg / cm2 within 5… 10 min and subsequent treatment of it with a solution of eluent containing, in g / L: ammonium chloride 80 ... 100 boric acid 8 ... 10 rest. The result is an increase in the degree of regeneration of the ionite.
