摘要
该分析方法是将锌样品经盐酸处理后,在动物胶、盐酸、氯化钾按一定比例配制的盐酸底液中,用1％抗坏血酸除氧,然后在示波极谱仪上于—0.2V～—0.8V的原点电位处,选择适当电流倍率进行铅、镉的同时测定。
Zinc sample treated by hydrochloric acid was put into the base liquid which consisted of animal glue hydrochloric acid and potassium chloride,with 1% ascorbic acid to remove oxygen. Then the
cadmium and plumbum contents in zinc at the point of -0.2^-0.8 volts original potential of the
oscillopolarography choosing appropriate current at same time were detected.
