水中痕量锑可以三、五价两种氧化物存在,同铬、砷、硒等变价元素一样,锑在环境中的迁移、转化规律及生物毒性效应随其赋存价态而异。近年来,用溶剂萃取、泡沫吸附、氢化物发生等方法分离测定水中微量锑(Ⅲ)和总锑已有报导。我们在用巯基棉富集多种微量元素、分离有机汞与无机汞、砷(Ⅲ)与砷(Ⅴ)的基础上,利用它对锑(Ⅲ)与锑(Ⅴ)吸附性能的明显差异,建立了巯基棉分离、富集-氢
Trace antimony in water can exist in three or five valences. Like chromium, arsenic, selenium and other valence elements, the migration and transformation rules of antimony in the environment and the biological toxicity effect vary with the state of valence. In recent years, the separation and determination of trace antimony (Ⅲ) and total antimony in water by solvent extraction, foam adsorption and hydride generation have been reported. Based on the enrichment of various trace elements with mercapto cotton and the separation of organic mercury and inorganic mercury, arsenic (Ⅲ) and arsenic (Ⅴ), we used the obvious difference of antimony (Ⅲ) and antimony (Ⅴ) Established a thiol cotton separation, enrichment - hydrogen
