Combination of multi-oxidation process and electrolysis for pretreatment of PCB industry wastewater and recovery of highly-purified copper

Current approach for wastewater treatment in the field of printed circuit board (PCB) is uneconomical and resource-wasting, which has turned into a heavy burden for the enterprise. Therefore, it is highly urgent to develop a cost-efficient and sustainable strategy for the remediation of PCB wastewater. In this work, a multi-oxidation coupled with electrolysis approach was proposed for the decontamination of PCB wastewater and recovery of copper...
