Speciation of chromium by the determination of total chromium and chromium (II) by electrothermal atomic absorption spectrometry



Speciation of chromium by the determination of total chromium and chromium (II) by electrothermal atomic absorption spectrometry



Journal of Analytical Atomic Spectrometry 8(4): 649-653



A method for the determination of chromium(III) and total chromium was studied. Chromium(III) was chelated with 0.1 mol l-1 quinolin-8-ol in methanol, extracted with isobutyl methyl ketone and determined by electrothermal atomic absorption spectrometry. The effects of the pH, extraction and heating time and amounts of reagents required for the extraction were studied. The detection limit of this method was 12 ng l-1.
