| 摘 要： | 利用反渗透技术将镀镍漂洗水浓缩分离,浓缩液补加到镀镍槽中,透过液在镀镍漂洗槽中循环使用。向镀镍槽中加入硫酸钾,提高镀液的导电性能,同时降低镀液中氯化镍的浓度,使镀镍过程中阳极溶解速度和阴极沉积速度相等。镀件在镀镍前和镀镍后都经过回收槽漂洗,使回收槽中镍离子的浓度保持不变。用过硫酸钠氧化和活性炭吸附浓缩液中的有机杂质,用氢氧化钾沉淀铁杂质,用电解法处理铜杂质,用电解法和锌抑制剂组合法处理锌杂质。采用这些措施后,可实现反渗透浓缩液的完全回收利用。

| Abstract: | Nickel plating rinsing water was concentrated with reverse osmosis technology.The concentrated liquor wass added to nickel plating baths and infiltrated water was circularly used in rinsing baths.Potassium sulfate was added to the nickel plating solution to improve its electroconductibility,and then the concentration of nickel chloride was decreased to make the anode dissolving rate be equal to the cathode sedimentation rate during electroplating.Workpieces were rinsed in the recovery baths before and after... |
