Abstract：
Selenium is an essential element for the normal cellular function of living organisms. However, selenium is toxic at concentrations of only three to five times higher than the essential concentration. The inorganic forms (mainly selenite and selenate) present in environmental water generally exhibit higher toxicity (up to 40 times) than organic forms. Therefore, the determination of low levels of different inorganic selenium species in water is an analytical challenge. Solid-phase extraction has been used as a separation and/or preconcentration technique prior to the determination of selenium species due to the need for accurate measurements for Se species in water at extremely low levels. The present paper provides a critical review of the published methods for inorganic selenium speciation in water samples using solid phase extraction as a preconcentration procedure. On the basis of more than 75 references, the different speciation strategies used for this task have been highlighted and classified. The solid-phase extraction sorbents and the performance and analytical characteristics of the developed methods for Se speciation are also discussed.
摘要：
硒是生物体正常细胞功能的基本要素。然而,硒的毒性浓度仅比必需浓度高3至5倍。环境水中存在的无机形式(主要是亚硒酸盐和硒酸盐)通常表现出比有机形式更高的毒性(高达40倍)。因此,测定水中低水平的不同无机硒是一个分析挑战。在确定硒物质之前，固相萃取已被用作分离和/或预浓缩技术，因为需要精确测量极低含量的水中硒物质。本文对已发表的使用固相萃取作为预浓缩程序的水样中无机硒形态形成方法进行了严格的评论。根据超过75个参考文献，用于此任务的不同物种形成策略已被强调和分类。还讨论了固相萃取吸附剂以及已开发的Se形态形成方法的性能和分析特征。
