摘要：

An ion-chromatographic procedure is described for the determination of selenium (VI) at μg L-1 level in the presence of anions and heavy metal ions. Maximum permissible concentrations and effects from each interfering substance were investigated for the Se concentration range 12.5-1,000 μg L-1. The method, optimized for the detection of SeO42-, gives results suitable for speciation analysis. Total selenium can be determined after complete conversion to selenate ion by oxidation with KMnO4. The detection limit of selenium is 4.8 μg L-1 (0.96 ng for 200 μL sample). © 1990 Friedr. Vieweg & Sohn Verlagsgesellschaft mbH.
