摘　　要：研究应用微波消解-原子荧光分析技术测定富硒油菜籽中微量硒的方法.样品经微波消解后，使用原子荧光谱仪测定样品中的微量硒.该方法检测出限为0.2 ng/mL，线性良好，线性相关系数〉0.999 8，回收率为94.8%-104.2%，铁氰化钾可有效消除其他共存金属的干扰.该方法具有快速灵敏和操作简单等优点，适用于油菜籽中硒的质量分数的测定.To study the methods for determination of micro - volume Selenium in rapeseeds by using microwave acid digestion system and Atomic Fluorescence Spectrometer, After the samples were digested by microwave acid digestion system,the micro- volume Selenium in the samples were detected by Atomic Fluorescence Spectrometer. The detection limit of the method was O. 2 ng/mL, the correlative coefficient was over O. 999 8, and the recovery fraction was 94.8% ~ 104.2% , potassium ferrocyanide was effectively used to eliminate interference of other metals. The method was rapid, sensitive and simple. It was useful for determining Selenium in Selenium -rich rapeseeds.
