文摘Summary-The combined derivative spectrophotometry developed bythis paper is a new method, which can be used for the simultaneous determination of mtulticomponent mixture and may be allowed to improve sensitivity and accuracy of the determination remarkably. Two practical tests were carried out to verify the correctness of the theory and the results were Satisfactory.This paper also made an approach to quantitative comparison of sensitivities of different methods, and the conception of the index of relative sensitivity has been proposed.
