摘要：

Beta correction absorbance can eliminate completely the interference from the excess of chromogenic reagent to give the real absorbance of the complex produced. The reaction of antimony and Chromazurol S was developed in pH 5-6 buffer solution. The determination of trace amounts of antimony in waste water was studied by beta correction spectrophotometry using this reaction. The results showed that Beer's law was obeyed over the concentration range O-1.0 mg l(-1) of antimony. The detection limit is 0.009 mg l(-1), which is low enough to determine antimony in environmental waters.
