摘要
本文研究了在盐酸介质中和CTMAB存在下,邻硝基苯基荧光酮(o-NPF)与锗(Ⅳ)、Nb(Ⅴ)、Mo(Ⅵ)、Ti(Ⅳ)的共同显色条件,提出了用PLS-分光光度同时测定多组分Ge、Nb、Mo、Ti的新方法.该法用于标准钢样和合成试样的分析,获得较为满意的结果.
In the presence of a catioaic surfactant ( CTMAB) and in a strong acid medium, the optimum condition for color reaction of o-nitrophenylfluorone with Ge ( Ⅳ ) , Nb( Ⅴ ),Mo ( Ⅵ ) and Ti(Ⅳ) has been investigated. Simultaneous determination of the foar elements by applying partial least squares (PLS ) spectrophotometric method has been also developed. Satisfactory results can be obtained for standard steel samples and synthetic samples by using of this method.
