摘要
利用同位镀汞膜代替预镀贡膜 ,通过标准实验研究了微分电位溶出分析方法测定微量锰的实验条件。结果表示该方法测定锰重现性好 ,灵敏度高 ,相性相关系数为 0 .9996,标准回收率为98%～ 10 4 % ,对具体的空气样品和水样实际分析 。
The experimental conditions are studied in the article,which involve determining micromanganese with the analytical method of differential potential ligature in a standard experiment by replacing mercury preplating film with isotope mercury plating film.The result shows that this method has a good reproduction and a high sensitivity in determining manganese.The relation coefficient is 0.9996,and the recovery ratio is 98%～104%,The result is satisfactory in analyzing air sample and water sample with the method.
