Title: Spectrophotometric determination of trace tinII in hot-dipped zinc alloy with 2,4-dichlorophenyfluorone
Abstract: In a acid medium,tinⅡ can instantly form a stable nacarat complex with 2,4-dichlorophenyfluorone in the presence of oxalic acid and TritonX-100,which can be determined by spectrophotomety.The maximum absorption of the complex is at 520 nm with molar absorptivity of 1.10×10~5 L·mol~(-1)·cm~(-1).Beer's law is obeyed in the range of 0~10 μg/25 mL for tinⅡ.The method has been applied to the determination of trace tin? in hot-dipped zinc alloy.
