Environment-friendly treatment method for recycling alloy electroplating liquid

Abstract

The invention belongs to the technical field of alloy electroplating liquid treatment, and particularly relates to an environment-friendly treatment method for recycling an alloy electroplating liquid. The environment-friendly treatment method comprises the following steps: 1, leading out the electroplating liquid, namely leading out the electroplated alloy electroplating liquid from an electroplating tank; 2, separating heavy metals: separating the heavy metals in the alloy electroplating liquid through a chemical agent, and taking out a heavy metal compound; and 3, cleaning and recycling: cleaning the heavy metal compound, and recycling the separated alloy electroplating liquid; wherein the second step is completed through cooperation of an alloy electroplating liquid recycling and reusing environment-friendly treatment device. According to the method, chemical agent can fully react with the alloy electroplating liquid, and the removal effect on heavy metal ions in the alloy electroplating liquid is improved; and heavy metal compounds generated after the reaction can be conveniently collected.

Description

technical field [0001] The invention belongs to the technical field of alloy electroplating solution treatment, and in particular relates to an environment-friendly treatment method for recycling and reusing alloy electroplating solution. Background technique [0002] Alloy electroplating is a process that uses the principle of electrolysis to attach a layer of metal film to the surface of metal parts. Alloy electroplating requires a low-voltage, high-current power supply that supplies power to the electroplating tank and an electrolytic device consisting of electroplating solution, parts to be plated and anodes. Electroplating solution refers to a liquid that can expand the cathodic current density range of the metal, improve the appearance of the coating, and increase the stability of the solution against oxidation. The composition of the electroplating solution varies depending on the plating layer, but they all contain the main salt that provides metal ions, the complexi...
