Abstract
Inventia se refera la un procedeu de obtinere a sulfatului de zinc de înalta puritate, necesar prepararii sulfurii de zinc pentru luminofori. procedeul realizeaza purificarea sulfatului de zinc tehnic, prin tratare cu o pasta oxidanta H2O2-ZnO, în vederea îndepartarii fierului, urmata de dislocuirea electrochimica cu pulbere de zinc si/sau complexarea celorlalti ioni impurificatori cu DMG si DDTG, cât si de adsorbtia complecsilor formati pe carbune activ.
