摘要
采用微波消解-氢化物发生原子荧光法(HG-AFS)测定灵芝孢子粉、超微康硒原粉及富硒大米中的硒含量,结果该法检出限为3 ng,线性范围为0.01～0.20μg,平均回收率为87.5%～101.2%(n=5)。该法简单、可靠、重现性好,灵敏度高。
This paper created a method to determinate selenium. Determinate selenium in Ganoderma lucidum spores Chaoweikang xiyuanfen and Selenium-enriched rice by microwave digestion HG-AFS method. The detection limit （DL） of the method was 3.0 ng,the linear range was 0.01 μg-0.2μg and the average recovery was 87.5%-101.2% （n=5）. The method was accurate, simple and well reproducible.
