摘要
以硫脲为掩蔽剂，加入到ＫＢＨ４中，以氢化物原子荧光法直接测定金矿床黄铁矿中硒的含量．结果表明，该法简便、快速，准确度高，适用范围在０．５－１０ｍｇ／Ｌ之间，加标回收率为９０％－１０５％
Using thiourea as a masking ingredient, and adding it to KBH4, deter minating the content of selenium in pyrite of a golden ore directly by hydride generation AFS, we get a result that this methed is simple and convenient, and has a high accuracy. The suitable range of content is 0.5 ~ 10mg/L.
