In this study, ion-exchange resins of the cation exchanger universal (KU)-2 type with functional sulfate groups, a carboxyl-containing cation exchanger of a carboxyl containing cationite (KB) type, and polyampholyte amphoteric carboxyl containing ion exchanger (ANKB)-35 were studied for Ni2+ and Cu 2+ ion extraction from water solutions. The high value of the ion-exchange capacity of the ionate KU-2 compared with the complex formation amphoteric ion-exchange resin ANKB appeared to be more suitable for use in wastewater treatment. The wet KU-2-20 resin has larger static ion-exchange capacity than other gel resins. This paper presents a technological circuit and installation for local treatment of rinsing water of nickel plating with subsequent metals utilization. It was found that the gradual accumulation of nickel occurs during multiple solution circulations with a low rate.
