摘 要: 本文根据铜氨络离子溶液的化学性质,对溶液pH值变化与氢氧化铜沉淀量的关系进行理论分析和计算机精确计算,确定回收氢氧化铜的最佳pH值,进而研究用硫化钠处理残余废液以达到排放标准的可行条件. According to chemical properties of copper ammoniate complex-ion solution, the relation of the deposition of copper hydr xide and pH of solution are analysed and exactly calculated with computer. The proper pH for recovering copper hydroxide was decided and the discharge standerd for residua wastewater treated with sodium sulfide is also studied.
