| Abstract: | Summary The capillary gas chromatographic determination of CrVI] besides CrIII] and of Co in Rhine water is described. The previously reported 9] optimized arrangement is used. Detection is performed with an ECD, extraction of the chelates from aqueous solution, pH 3, is carried out with a solid phase extraction system. The detection limits of CrVI] and Co are 0.05 ppb and 0.2 ppb, respectively.
