In the paper, it discussed the content of the application chromazurol - S as a chromogenic reagent to measure aluminum content of steel in pH=4-6 weakly acidic solution medium . with the help of a few graphical representations on key issues （the choice of wavelength）, it describes ＆ analyzes various influencing factors which affect the application of chromazurol -- S colorimetric determination, and makes reserch on how to eliminate.by practical experiments on several standard steel samples, finally, obtained a simple method that Can be used for the determination of aluminum in the steel, proven to be fast and reliable.
