| Abstract: | The computation method and the differences between components are the dominated factorswhich affect the accuracy of an analytical determination with computation spectrophotometry.Computational-derivative spectrophotometry, based on taking advantage of the higher resolu-tion of derivative spectrum, was proposed for the simultaneous determination of multicompo-nents. The additivity of derivative spectra and the selection of measuring points are impor-tant factors for this method. The measuring points were selected in different order deriva-tive spectrum according to the condition number of the coefficient matrix. The concentrationsof the components were calculated by solving a group of equations. The analytical applicationof the method to the W/Mo-SAF-CTMAB proves that the method is quite simple andaccurate. |
