Abstract

The tetravalent and hexavalent selenium content of water samples can be determined by conventional energy-dispersive X-ray fluorescence after different preconcentration steps. Selenium values of nearly three-hundred different environmental and drinking water samples in Belgium are reported. The results are quite low, ranging from the detection limits up to 1 microgram 1-1. The concentration levels are compared to literature data and the speciation is discussed. The contribution of drinking water to the daily intake of selenium in Belgium ranges from less than 0.2 to 5%.

摘要

通过不同的预浓缩步骤后，利用传统的能量色散X射线荧光分析法可测定水样中的四价和六价硒含量。本文报道了比利时近三百个不同环境水样和饮用水样的硒含量值。结果相当低，范围从检测限到1微克/升。将这些浓度水平与文献数据进行了比较，并对硒的形态进行了讨论。在比利时，饮用水对每日硒摄入量的贡献范围为不到0.2%至5%。
