火焰原子吸收微量进样法测定耳血中Cu、Zn、Ca、Mg和Fe

FLAME ATOMIC ABSORPTION SPECTROMETRY DETERMINATION OF ZINC AND FERRUM IN ENAMEL

本文利用原子吸收分光光度法采用微量注射进样，测定耳全血中Ｃｕ、Ｚｎ、Ｃａ、Ｍｇ和Ｆｅ的含量。结果表明、方法回收率在９６％以上，样品测定的相对标准偏差Ｚｎ、Ｃａ、Ｍｇ和Ｆｅ小于２％，Ｃｕ为３．９％。本方法快速、准确，仅需１０μＬ耳血即可获得五种生命元素含量的满意结果。

The amount of zinc and ferrum in enanmel was determined by flame AAS.For twenty six healthy men,the average of zinc and ferrum were 325 6±84 8 and 34 7±9 1μg/g,respectively.For fifty four patients with dental caries disease,the average of zinc and ferrum were 269 9±63 5 and 38 7±10 0μg/g ,respectively.The difference between healthy men and patients of zinc and ferrum rate was insignificant.As to the determination method,the rate of recovery varied from 97 0 to 101 5% for zinc and from 97 2 to 102 4% for ferrum. The RSDs fo Zn and Fe are less than 2 60 and 2 10% respectively.
