选择沉淀法分离电镀废水中铜和镍的研究

Studies on Separation of Copper and Nickel in Electroplating Waste Water with Selected Deposition Methord

用硫化钠选择沉淀法分离电镀废水中的Cu2+和N i2+离子,根据热力学理论阐述Cu2+和Ni2+分离的原理,确定分离的适宜条件。将理论分析与实验研究的结果进行对比,二者基本上吻合,表明热力学理论对电镀废水中重金属离子的分离有实际指导意义。

Na2S selected deposition was used in the separation of Cu^2＋ and Ni^2＋ in plating waste water of given chemical plant. The optimum separation conditions was confirmed according to the theory of thermodynamics. The experimental result was accord with the theory which mentioned above, it was implied the theory of thermodynamics has very important instructed signification in separating the heavy metal ion from plating waste water.
