摘 要：
In order to make people better control and regulate the intake of selenium,the contents of selenium in Tongren pearl peanut were determined by ultraviolet spectrophotometry.The results showed that the contents of selenium in Tongren were 20.54 μg/g.According to the experimental datas,the relative standard deviation was 0.73%.The recovery rate of standard selenium in selenium samples was between 96.5% and 98.1%,the average rate was 97.4%,the relative standard deviation was 0.75%,and the recovery effect was good.This analysis method was feasible and accurate.
