摘要
对铜在Cu(Ⅱ)-NH3-(NH4)2SO4-H2O体系中的溶解行为进行了研究,分析了影响铜溶解速率的因素。实验结果表明,溶液中初始铜离子浓度、氨和硫酸铵浓度、温度以及空气通入量均对铜的溶解速率有较大的影响。得到了较适宜的溶铜条件:温度50℃,初始铜离子和氨的浓度分别为1.0mol/L和7.5mol/L,硫酸铵浓度为0.5mol/L,同时通入适量的空气。
The dissolution behavior of copper in Cu （Ⅱ）-NH3-（ NH4）2 SO4-H2O system was studied. The factors of affecting the dissolution rate of copper were analyzed. Experimental results showed that the dissolution rate of copper was influenced by initial concentration of cupric ion and ammonia, concentration of ammonium sulphate, temperature and amount of air entering the system. The suitable conditions of dissolving copper were given as follows ： temperature at 50℃ ; initial concentration of cupric ion around 1.0mot/L; ammonia concentration around 7.5mol/L; concentration of ammonium sulphate around 0.5mol/L and air in appropriate amount.
