摘要
研究用硼氢化钾还原-分光光度法测定植物性食物中的硒.结果表明:方法的相对误差小于0.6%,变异系数不大于1%,回收率在96%~103%之间.
Spetrophotometric determination of selenium in the vegetable food with potassium borohydride reduction is studied.The results show that the relative error is less than 0.6%,coeffcient of variation is not more than 1% and recovery is in the range from 96% to 103%.
