Determination of 18 Trace Elements in Chinese Traditional Medicine by ICP-OES

Xia Shen

Abstract

18 kinds of trace elements(Al,As,B,Ba,Ca,Cd,Cr,Cu,Fe,Mo,Mg,Mn,Na,Ni,P,Pb,Sr,Zn) of Chinese Traditional Medicine were determination by Inductively coupled plasma optical emission spectrometry(ICP-OES) with microwave digestion.Besides As,Cd,Mo and Pb,the elements relative standard deviation(RSD) is almost less than 5% and the elements recovery of standard addition is between 95%~106%.The method is simple,rapid and accurate.
