| 摘 要： | 应用ＡＦＳ－２２０１型双道原子荧光光谱仪对氢化物发生原子荧光法测定食品、水产品及饲料中微量元素硒的方法进行研究。采用改进的ＨＮＯ３－ＨＣＩＯ４湿式消解法消解样品，并对各种最佳分析进行探讨和验证。方法的检出限为０．４ｎｇ／ｍｌ，线性范围为０～４００ｎｇ／ｍｌ，回收率为８８．４％～９８．５％。用标准物质对照，其测定数据完全在标准值范围内，该方法具较多优点，适于各种含硒样品的测定。

| Abstract: | A method for determining the content of Se in food, seafood and feed has been studied by using AFl 2201 type double-beam hydride generation- fluorescence spectrum (HG- AFS ). During the preftrninary treat ment, the samples were digested with a modified method of HNO3-HClO4 wet oxidation. The optimal conditions of all analytical factors were discussed and tested. The detection limit is 0. 4 ng/ml, and the recovery rate is 88. 4 % -- 98. 5 %, and the linear range is 0 - 400ng/ml. The values of Se content determined in standard samples are in the standard range. The method has many advantages in determining micro-Se in various samples. |
