摘　　要：研究了镀镍漂洗水反渗透回收液中杂质的处理方法。对有机杂质的处理是回收液能否回用的关键。用过硫酸钠氧化有机物,并用活性炭吸附,能够有效地去除回收液中的有机杂质。Fe2+杂质被氧化成Fe3+离子,Fe3+离子水解生成氢氧化铁沉淀。用硫化钾沉淀法去除回收液中的铜杂质。用络合剂掩蔽锌杂质,消除其对镀液的影响。生产实践表明,用这些方法处理后,将反渗透回收液补加到镀镍槽中,对镀液的性能没有不良影响。Impurities treatment methods for reverse osmosis recovery solution of nickel plating rinsing water were studied.Organic impurities treatment is a key technology for reuse of the recovery solution.Oxidizing the organics with sodium persulfate and absorbing them with active carbon can effectively remove the organic impurities from the recovery solution.Fe2＋ impurity could be oxidized to Fe3＋ ions,and then Fe3＋ ions could be hydrolyzed to produce ironic hydroxide.Copper impurity could be precipitated with potassium sulfide.Zinc impurity could be masked with a complexing agent to eliminate its bad effect on nickel plating.Production practices indicate that,there is no reverse effect on performance of the nickel solution during use of the recovery solution treated with these methods.
