原子荧光光度法测定青海海东某地富硒大蒜中微量硒

Determination of Trace Selenium in Se-enriched Garlic Somewhere Haidong City of Qinghai Province by Atomic Fluorescence Spectrometry

硒是人体必需的微量元素,而大蒜是最能富硒的植物,青海海东市作为富硒紫皮大蒜的主产地,大蒜中硒含量的测定具有十分重要的意义。用硝酸-高氯酸分解样品,原子荧光光度法测定富硒大蒜中的微量硒。其方法检出限为：0.01μg/g,相关系数为：0.9999,硒的回收率为：90%~105%。该方法具有操作简单、灵敏度高、线性范围宽、快速准确可靠等优点,适合广泛使用。

Selenium are essential trace elements, and is the most can Se - enriched garlic plant, Haidong city of Qinghaiprovince as selenium - rich purple skin garlic producers, the determination of selenium in garlic has the very vitalsignificanceo The samples were decomposed with HNO3 - HC104, a method for determination of trace selenium in garlic byatomic fluorescence spectrometry. The detection limit of the method was 0.01 ug/g, correlation coefficient was 0.9999, therecovery rate of selenium as follows ： 90% -105%.
