Scope

Scope: This standard specifies the requirements for the comprehensive utilization and deep processing of PCB etching wastewater, the production processes of alkaline etching solutions, single-liquid acidic etching solutions, and dual-liquid acidic etching solutions, as well as the production of copper sulfate monohydrate and copper sulfate anhydrous. This standard applies to the comprehensive utilization and deep processing of PCB etching wastewater, and the recycled products obtained therefrom. Main technical content: This standard uses PCB etching wastewater as the raw material (hazardous waste code: 397-004-22, 397-005-22, 397-051-22). After extracting copper, the mother solution undergoes necessary processing and is supplemented with additives to produce alkaline etching solutions, single-liquid acidic etching solutions, and dual-liquid acidic etching solutions. The copper extracted from the etching wastewater is processed into copper sulfate monohydrate and copper sulfate anhydrous.
