摘　　要：氢化物－电热原子化装置测定人血清中硒，可减少试样中基体的干扰，有良好的线性关系，方法灵敏度为１．２μｇ／Ｌ／％，检测限０．４μｇ／Ｌ，变异系数６．３％。具有用血量少、方法简便、灵敏度高。Selenium in serum has been determined with electric-heating atomic absorption-hydride instrument. The method can eliminate interference in matrix and has satisfy linear-relation. The sensitvity of the method is 1.2 μg/L, detective limitation 0.4 μg/L and variance 6.3 %. It also has advantages of less volume of blood sample, easy operation, high sensitivity and satisfy accurancy.
