AbstractChromium valence states in yeast biomass are investigated by X-ray absorption near-edge structure spectroscopy (XANES) using an upgraded experimental method. The main advantage of this new XANES method is to record the transmission and fluorescence experimental data simultaneously in a same ion chamber. Such method is very convenient to analyze a series of unknown chromium valence state samples ( e. g. relatively low Cr concentration with fluorescence mode) comparing with a standard sample (Cr2O3) using transmission mode, in order to avoid systematic error associated to the uncertainty of the edge energy induced by the different experimental operating condition. The experimental results show that in yeast biomass almost all Cr(VI) is reduced to Cr(III) addressing the potential use of biomass for chromium reduction.
