| Abstract: | A way that the acidic etching solution with the alkaline etching solution were mixed and deposite copper to prepare the copper oxide has been adopted, and the influence of the acidity to deposition was discussed; Meanwhile ,the adjustment of the index that the mother solution of the copper deposition returned to use for the alkaline etching solution and the etch rate have been studied, and the wastewater has been used repeatedly,and it was a perfect method to recycle circuit board wastewater and recycle the copper. |
