Abstract:

The highly concentrated Ni²⁺ could be found in the man-made diamond was tewater that causes serious pollution to the environment,but is worthy of reuse .It is shown that some processes of electrolysis,such as ion exchange concentr ation,adjusting pH value and extending cathode could recover 99% of Ni²⁺.Envir onmental and economic benefits can be gained in the recovery process

Key words: ion exchange, electrolysis, extending cathode

摘要：

人造金刚石生产废水中含有较高浓度的镍离子,对环境有严重的污染,但又具有一定的回收价值。采用离子交换浓缩、调整溶液pH值、扩展阴极电解回收工艺可以将废水中99%的镍回收。回收过程可取得良好的经济效益。
