Abstract: Principle, experiment and datum treatment method of stepwise regression analysis were introduced.Simultaneous determination for multicomponent mixture was discussed spectropho-tometrically.By using the method, the results obtained from the samples containing several nitrophe-nols are satisfactory.This method is useful when the scope of possible existing components in sample can be known, but how many components are unknown.This method is simple, rapid and reliable.

Key words: Stepwise regression analysis, Multicomponent sample, Spectrophotometry, Nitrophenols
