Влияние концентрации NH4CL на состав пигментов, полученных из отработанных аммиакатных электролитов цинкования

Abstract

It is proposed to separate waste water from galvanic production in order to reduce its impact on the environment. Spent galvanizing electrolytes have been proposed to be used to produce white pigments by precipitation with Zn2+ sodium phosphate. The dependence of the composition of the obtained pigments on the concentration of NH4Cl in the spent electrolyte was studied.
