Copper electrorefining is a key part of copper metallurgical processes. The electrolyte is usually purified to prevent the accumulation of impurities and contamination of the cathode. Cyclone electrowinning is a widely applied purification method, but black copper mud that contains arsenic is produced after the process and endangers the environment. With the addition of effective chelators, controllable electroplating can be achieved. In order to investigate their role in electrodeposition, a variety of chelators were selected and applied in this study. LSV, XRD, and SEM were used to characterize Cu-As alloys produced from each test. The effects of chelators on the number and shifting of phase transition zones during the electrodeposition were analyzed.

螯合剂在铜电解液电沉积铜砷合金中的作用

铜电解精炼是铜冶金工艺的关键部分。电解液通常经过净化，以防止杂质积聚和阴极污染。旋风电积是一种应用广泛的提纯方法，但处理后会产生含有砷的黑铜泥，危害环境。通过添加有效螯合剂，可实现可控电镀。为了研究它们在电沉积中的作用，本研究选择并应用了多种螯合剂。LSV、XRD 和 SEM 用于表征由每个测试生产的 Cu-As 合金。分析了螯合剂对电沉积过程中相变区数量和位移的影响。
