Electrothermal atomic absorption spectrometric determination of Cr(VI) during ferrochrome production

The level of the generation of hexavalent chromium during ferrochrome production was checked. The concentration of Cr(VI) increases with each stage of ferrochrome production, 7070 μg g −1 being the highest concentration encountered in the last stage of production (dust). This concentration exceeds t...
