Determination of Copper in Ejiao by Flame Atomic Absorption Spectrometry

Zheng Jian-ming

Abstract

A new method was described for the determination of copper in Ejiao,by flame atomic absorption spectrometry with microwave digestion.The advantages of microwave digestion were convenient,quick,less contamination,and the samples were digested completely.The detection limits was 0.006 μg/mL,the recovery percent was 97.8%~108.0%,and the relative standard deviations was less than 2%.The results were satisfactory.
