摘要
硒的形态研究是了解环境中硒的毒性、生物可利用性、迁移和生物地球化学循环等方面的基础,其研究方法一般分为直接和间接法。本文总结了环境中硒形态的研究方法,特别是对环境样品中常用的硒形态分析技术——连续化学浸提技术作了全面详细的讨论,并综述了其它硒形态分析方法的最新动态。
Toxicity, mobility and bioavailability of selenium are controlled by chemical speeiation in the environment. Determination of Se speciation is a key aspect to understand its biogeochemistry cycle and potential environmental consequence. The speciation analysis of selenium in environmental samples, which are summarized in this paper, is commonly divided into direct or indirect method. In particularly, the sequential chemical extraction technique, which was commonly applied on selenium speciation in the environment, was discussed in great details. Meanwhile, the trends of other methods were also reviewed.
