本文采用ＳｅＳＯ２－３－ＫＩＯ３体系示波极谱催化波法测定了鸡蛋中的硒。试样经ＨＮＯ３－ＨＣｌＯ４混酸消化处理，用浓盐酸还原为Ｓｅ（Ⅳ）后，进行示波导数极谱测定。该方法线性范围为０．０５～２．５０μｇ／Ｌ，回收率９５％，对样品测量的相对标准偏差为４．７６％。
In this paper, SeSO2-3-KIO3 system oscillopolarographic catalytic wave method for the determination of selenium in eggs. The sample was digested with HNO3-HClO4 mixed acid and then reduced to Se (Ⅳ) with concentrated hydrochloric acid. The linear range of this method is 0.05 ~ 2.50μg / L, the recovery rate is 95%, and the relative standard deviation of measurement to the sample is 4.76%.
