以Schiff碱新螯合树脂除去光亮镀镍液中的Cu^(2+)杂质

Removal of Trace Cu^(2+)from Nickel Electroplating Solution Using New Type of Chelate Resins

经实验证明,我们合成的四种 Schiff 碱新螫合树脂是 Cu^(2+)的优良吸附剂.将其应用于光亮镀镍电镀溶液中除去微量 Cu(2+)杂质,效果良好.将它们应用于废水中微量 Cu(2+)的回收,效果亦佳.

It is proved through experiments that four new type Schiff base macroporous chelate resins,PSVA, PMSVA,PHNVA and PSB synthesized by us are good adsorbant for copper ion Cu^(2+).Their effect of re- moval of trace Cu^(2+)from bright nickel electroplating solution is good.The results of the application of these resins for recovering Cu^(2+)from effluent are also excellent.
