| 摘 要： | 在０．６０ｍｏｌ／Ｌ醋酸－０．００２０ｍｏｌ／Ｌ对氨基苯磺酸介质中，Ｓｅ（Ⅵ）－对氨基苯磺酸配合物于－０．６３Ｖ处产生一敏锐的单扫描示波极谱波。硒含量在０．３－８０ｎｇ／ｍｌ范围内与波高有线性关系，检出限达０．１５ｎｇ／ｍｌ。利用该波测定实际试样中痕量硒，结果较好。

| Abstract: | In 0. 60mol/L acetic acid medium, the complex of Se (IV) and sulfanilic acid exhibits a sensitive and selective oscillopolarographic wave at - 0. 63 V vs. SCE. This provides a new oscillopolarographic method for the determination of Se in the range of 0. 3-80ng/ml. The detection limit is achieved at 0. 15ng/ml. Se in real samples was analysed by this method, with satisfactory results. |
