| Abstract: | This paper describes a multipurpose method of utilizing peroxid micro-etching waste liquid,and prepars basic copper carbonate by using micro-etching waste,crude copper oxide and sodium carbonate under the process of neutralization,iron removing and reaction.The experiment shows that iron impurities can be absorbed by metatitanic acid.When absorption time is 1 hour and the metatitanic acid is 250 g per liter micro-etching waste,the appropriate reaction condition of preparing basic copper carbonate is 70 ℃ and pH 8.5.Under that condition,the quality of the product can meet the chemical purity standards of HG 3-1075—77. |
