TN24: Determination of Chromium by Ion Chromatography Be the first to rate this application

determination chromium


Three methods are presented here for the determination of Chromium in various matrices. Method A utilizes a postcolumn reaction (PCR) with a color reagent. It is a very selective and sensitive method, allowing determination of Cr(III) & Cr(VI) at ppb levels. Method B also utilizes a PCR, but determines Cr (VI) only. It is used for industrial waste waters, analyzing samples that have undergone standard oxidation. Method C allows the determination of inorganic anions in addition to chromate by chemically suppressed conductivity. Please refer to AN1116, AU144, AU165 and AU179 for updated methods.
