摘　　要：利用组合导数分光光度法,用高灵敏显色剂水杨基荧光酮(SAF),在表面活性剂 CTMAB 存在的强酸性介质中,对钼、钛的同时测定进行了详细研究。解决了重叠谱带相互干扰的问题。对合金钢中的微量钼、钛进行了同时测定,结果满意。Using the combined derivative spectrophoto- metry,the simultaneous determination of mo-lybdenum(Ⅵ)and titanium(Ⅳ)has been studiedin the presence of salicylfluorone(SAF)andcetyltrimethyl ammonium bromide(CTMAB).Theproblems of overlapped spectra,in both normalabsorption spectra and derivative spectra.havebeen overcome.This method has been used inthe rapid determination of micro amount of Moand Ti in some steel alloys with satisfactoryresults.
