| 中文摘要 |
| 在0.60mol/L醋酸-0.0020mol/L对氨基苯磺酸介质中,Se(Ⅳ)-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. |
| 英文摘要 |
| 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. |
