原子吸收法测定藏鸡蛋壳中钙、镁、铁含量

The Determination of Ca,Mg,Fe in Tibetan Egg Shell by Flame Atomic Absorption Spectrometry

为研究藏鸡蛋壳的成分,实验以盐酸溶解试样,超声波提取,火焰原子吸收光谱法测定藏鸡蛋壳中钙、镁、铁的含量。实验结果表明藏鸡蛋壳中的钙、镁、铁的含量分别为41.86%、0.35%、0.0128%,其中钙、铁的含量均高于普通鸡蛋壳,藏鸡蛋属于天然绿色农副产品,其壳可作为原料,进行进一步开发利用。

In order to study the contents of Tibetan egg shell, the determination of Ca Mg Fe in Tibetan egg shell by flame atomic absorption spectrometry （FAAS） with uitasonic wave-acid extraction was studied. The results indicated that the calcium and iron in Tibetan egg shell were higher than that in ordinary egg shell, and the contents of calcium, magnesium and iron in Tibetan egg shell were 41.86% , 0. 35% , 0. 0128%. Tibetan egg is natural green agricultural product, its shell can be used as raw material for further development and utilization,
