火焰原子吸收光谱法测试黄花菜中的钙、锌、铜

Determination of Calcium and Zinc and Copper Content of Day Lily by Flame Atomic Absorption Spectrometry

建立了火焰原子吸收光谱法测定黄花菜中钙、锌、铜含量的方法。该方法的检出限量 :钙为 0 .0 3ug/g ,锌为0 .0 2ug/g ,铜为 0 .0 1ug/g ;平均加标回收率 :钙为 99.1% ,锌为 99.7% ,铜为 99.8%。本方法可用于不同产地黄花菜中钙、锌。

A method for the determination of Ca and Zn and Cu content of Day Lily by flame atomic absorption spectrometry is established.The detection limits is found to be 0.3ug/g for Ca and 0.02ug/g for Zn and 0.01ug/g for Cu.The average recoveries of standard additon are 99.1% for Ca and 99.7% for Zn and 99.8% for Cu.The method can be applied to the deter mination of Ca and Zn and Cu content of the Day Lily in different placws.
