| 摘 要： | 痕量钨、钼与芦丁在混合表面活性剂（ＣＴＭＢ＋Ｂｒｉｊ－３５）存在下，于ｐＨ５．４ＨＡｃ－ＮａＡｃ介质中发生灵敏的显色反应，但形成的胶束配合物的吸收峰严重重叠，应用双波长系数倍率法同时测定了混合样中的两组分。

| Abstract: | There are sensitive chromogenic reactions of trace Mo (VI) and W (VI ) with rutinin the presence of cetyltrimethylammonium bromide and Brij-35 at PH 5. 4 HAc-NaAcmedium and the absorption spectra of the formed micelle complexes overlap seriously.Spectrophotometic determination of two trace components in simulation samples wassuccessfully made by using K-factor dual-wavelength method. |
