通过对两种样品前处理方法的比较,建立了微波消解-原子荧光光谱法测定鸡蛋中硒的方法。该方法测定硒的线性范围为0～250ng/mL,相关系数r=0.9994,检出限0.24ng/mL,回收率98.29%～128.57%。方法快速准确。实验结果表明,普通鸡蛋中硒含量约为0.18mg/kg,富硒鸡蛋中硒含量约为0.51mg/kg。 By comparing the two sample pretreatment methods, the method of microwave digestion - atomic fluorescence spectrometry was established for the determination of selenium in eggs. The linear range of selenium was 0 ~ 250 ng / mL, the correlation coefficient was 0.9994, the limit of detection was 0.24 ng / mL and the recovery was 98.29% ~ 128.57%. Fast and accurate method. The experimental results show that the average selenium content of eggs is about 0.18mg / kg, selenium content of selenium-enriched eggs is about 0.51mg / kg.
