摘要
以导数微分脉冲极谱法对锌和镍共存液的重叠极谱波进行了解析处理 ,较好地消除了背景残余电流的干扰 ,采用零交点法对电镀镍液中少量杂质锌进行了测定 ,方法简便 ,相对偏差小于 2 %。
First\|derivative polarographic method combined zero\|crossing point approach was studied and applied successfully to resolve over lapping polarographic waves of zinc and nickel. Satisfactory quantitative results were obtained in the determination of zinc in nickel plating baths.
