用巯基棉富集环境水样中的微量CH_3Hg~(1+)、Hg~(2+)和Cd~(2+)等已有报道。但将巯基棉作为一种还原剂来富集微量金属和非金属离子(如Cr~(6+)和Se~(4+)、Se~(6+)等)尚无见到报道。作者在用X-射线光电子能谱(XPS)研究巯基棉对水样中的CH_3Hg~(1+)和Hg~(2+)、Se~(4+)和Se~(6+)及Cr~(3+)和Cr~(6+)的吸附作用时发现 Enrichment of trace amounts of CH_3Hg ~ (1 +), Hg ~ (2+) and Cd ~ (2+) in environmental water samples with sulfhydryl cotton has been reported. However, the use of thiols as a reducing agent to enrich trace metals and nonmetal ions (such as Cr 6+ and Se 4+, Se 6+, etc.) has not yet been reported. In this paper, XPS and XPS were used to study the effect of sulfhydryl cotton on CH_3Hg ~ (1+) and Hg ~ (2 +), Se ~ (4+), Se ~ (6+) and Cr ~ (3+) and Cr ~ (6+) adsorption was found
