微量元素硒在医学领域有着十分重要的生物学意义,人体摄入硒的不足或过量会导致疾病的发生,据文献克山病和大骨节病的发生同低硒有密切关系,所以微量硒的准确测定为医学界所重视[1-2]。一般常用的测定硒的方法有分子荧光法、原子吸收分光光度法等[3]。氢化物原子荧光法(HG- Trace element selenium in the medical field has a very important biological significance of human intake of selenium deficiency or excess can lead to the occurrence of the disease, according to the literature Keshan disease and Kaschin-Beck disease is closely related with the occurrence of low selenium, so trace selenium Accurate determination of the medical community attention [1-2]. Commonly used methods for the determination of selenium molecular fluorescence method, atomic absorption spectrophotometry [3]. Hydride atomic fluorescence spectrometry (HG-
