chemonite

Preparation of copper arsenite from waste acid containing arsenic and its application in copper electrolyte purification;

含砷废酸制备亚砷酸铜及其在铜电解液净化中的应用

The electrolyte was purified by copper arsenite to effectively remove Sb and Bi impurities in the copper electrolyte.

为有效脱除铜电解液中的Sb、Bi等杂质,采用亚砷酸铜净化电解液。

Arsenic trioxide was made by means of evaporating and cooling leaching solution after copper arsenite was mixed with water and copper arsenite was reduced by SO2.

使用氢氧化钠调节含砷废水pH为6,过滤后加入硫酸铜,采用氢氧化钠调节pH为8,经沉淀、过滤、洗涤得到绿色亚砷酸铜粉末。
