Abstract: Amethod of sequential determination of Cr ( Ⅵ) and T-Cr by FIA-SPin water was developed. The Cr( Ⅵ ) was directly measured with DPCby FIA-SPanalysis and the determination of T-Cr was carried out after the pre-oxidation of Cr( Ⅲ ) to Cr(Ⅵ) with PbO2 column at 80℃ before sample injection.Using the method described in this paper Cr( Ⅵ) or T-Cr can be determined at the concentration rangeof 0.05 - 3.0 mg/L. The sampling rate is 120 and 200 h-1 for T-Cr and Cr ( Ⅵ ) respectively.This method was applied to practical samples and the results obtained is satisfactory.
