Summary Simultaneous Determination of Chromium(VI) and Chromium(III) by Flame Atomic Absorption Spectrometry with a Chelating Ion-Exchange Flow Injection System A simple method is described for the simultaneous determination of chromium(VI) and chromium(III) in a flow injection system comprising chelating ion-exchange and flame atomic absorption spectrometry. Sampling rates for 200μ1 and 1 ml sample volumes were 120 and 60 h−1 (240 and 120 speciations per hour), respectively. Typical relative standard deviations were 0.52% for Cr(VI) (0.50μg ml−1 and 0.67% for Cr(III) (0.10,μg ml−1) and the corresponding limits of detection were 85 ng ml−1, and 16 ng ml−1, respectively.
