微量进样火焰原子吸收法测定血球血浆中锌的含量

Determination of Zn in Blood Corpuscle and Plasma by Flame Atomic Absorption Spectrophotometry(FAAS) with Micro-Sampling

本文介绍了在国产ＷＹＸ－４０２型原子吸收分光光度计上，用微量进样测定血球、血浆中Ｚｎ的含量，获得了与常规原子吸收法相同的灵敏度。一次测定的进样量为３００μＬ，测得血球中锌的平均回收率为９７．９％，相对标准偏差为３．４％，血浆中锌平均回收率为１００．８％，相对标准偏差为３．３％。

The determination of Zn in blood corpuscle and plasma by fiame atomic absorption spectrophotometry(FAAS) with micro-sampling is described in the present paper.The sensitivity of this method is same with convention method.The sample amount is 300μL,the recovery of Zn in blood corpuscle is 97.9%,the variation coefficient is 3.4%,the recovery of Zn in bloed plasma is 100.8%,the variation coefficient is 3.3%.
