英文摘要	Chromogenic agent alizarin red S was applied as complexant for the quantitative determination of trace aluminum by ultraviolet spectrophotometer. The experimental parameters (pH of the aqueous solution, temperature and the reaction time), interference in the measurement was optimized. The maximum absorbance of the reaction system was 490 urn further than the one of alizarin red S itself. The calibration curve was linear over the concentration range 0.04 similar to 0.14 mg.mL(-1) of aluminum with good precision as well as accuracy and the variance reached to 0.9803. The detection limit was down to 0.004 mg.mL(-1). Method Validation showed that: Fe3+ and Cu2+ had some influence on determination of Al3+, while K+, Na+ had little interference. The recoveries were 82%similar to 108%. Results from experiments indicated that the proposed method was easy for operation with great selection, reproductivity and comparison as well as board range of detecting concentration.
