Determination of Trace Elements for Angelica Sinensis by ICP-OES with Microwave Digestion

Xia Shen

Abstract

18 kinds of trace elements of Chinese herb Angelica Sinensis were determination by inductively coupled plasma optical emission spectrometry(ICP-OES) with microwave digestion.The descending order of the content of these trace elements is K,P,Ca,Mg,Fe,Al,Na,Zn,Cu,Mn,Sr,B,Ba,Cr,Ni,Pb,Cd,As.Besides Pb,Cd and As,the elements relative standard deviation(RSD) is less than 4.076% and the elements recovery of standard addition is between 96%～106%
