Abstract

Inventia se refera la un procedeu de preparare a hidroxizilor de cupru si zinc din deseuri, care sînt dizolvate în solutie carboamoniacala ce contine 8% CO2 si 16% NH3, produsele rezultate se descompun termic, sub vid, rezultînd oxizii de Cu si Zn care apoi se dizolva în acid azotic 49...50% sub agitare, astfel ca sa se obtina o solutie cu pH=1, careia i se adauga NaOH 20% în prezenta unei substante tensioactive, neionice si a lignosulfonatului de calciu rezultînd o suspensie stabila cu pH 6...6,5 ce contine hidroxizii respectivi.
