硒是人体必需的微量元素 ,在人的肌体内参与许多重要的代谢过程 ,缺硒会导致某些疾病。近年来 ,补硒品的研制倍受关注。但人体摄入过量硒会引起中毒。因此 ,建立硒的快速、准确的测定方法具有重要意义。硒的传统测定方法是荧光光度法[1 ] 。该法操作烦琐 ,所用试剂毒性大。近年
Selenium is an essential trace element in the human body and participates in many important metabolic processes in the human body. Selenium deficiency can cause certain diseases. In recent years, the development of selenium products has drawn much attention. However, excessive intake of selenium in the human body can cause poisoning. Therefore, the establishment of fast, accurate determination of selenium is of great significance. The traditional method of determination of selenium is fluorescence spectrophotometry [1]. The method is cumbersome to operate and the reagents used are very toxic. in recent years
