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。
The simultaneous determination of molybdenum and titanium was studied in detail using the combination of derivative spectrophotometry and salicylfluorone (SAF), a highly sensitive reagent, in a strongly acidic medium in the presence of surfactant CTMAB. Solve the problem of overlapping bands interfere with each other. The content of trace molybdenum and titanium in alloy steel was measured simultaneously with satisfactory results.
