摘要
痕量钨、钼在混合表面活性剂（ＣＴＭＡＢ＋Ｔｗｅｅｎ－６０）存在下，与４，５－二溴羟基苯基荧光酮发生灵敏的显色反应，所形成的胶束配合物的吸收峰严重重叠。应用小波变换同时测定了混合样中的两组份。
There are sensitive chromogenic reactions of trace W(Ⅴ) and Mo(Ⅵ) with 2,3,7 trihydroxy 9 dibromo hydroxyphenylfluorone (DBHPF) in the presence of cetyltrimethylammonium bromide and Tween 60, and the absorption spectra of the formed micelle complexes overlap seriously. Spectrophotometric determination of two trace components in simulation samples was successfully made using wavelet transform with satisfactory results.
