| 摘 要： | 根据电势-pH图可判断有关物相能够稳定存在的条件及相互间反应的趋势,这在湿法冶金、腐蚀与防腐及化工生产中有广泛应用.根据文献数据计算并绘制出Cu-H2O系的E-pH图,然后将之用于指导含铜电镀废水处理时工艺条件的选择,并与实验数据进行对比,两者基本吻合,这表明E-pH图对电镀废水处理有实际指导作用.

| Abstract: | the condition of steady-going presence and trend of reaction each other for relational substance can be judged from potential-pH diagram,This is widely applied in chemical production,corrosion and anticorrosion,hydrometallurgy.In this article,the potential-pH diagram of Cu-H2O system was drawn by means of data of literature or account,then it was applied to confirm the suitable technical condition when treatment of electroplating waste water contains copper.The result from potential-pH diagram matches well ... |
