Determination of Trace Elements in Zixuesan by Microwave Digestion and ICP-AES

Ming-Yu Chen

Abstract

Zixuesan was digested with HNO_3-H_2O_2 system by microwave digestion.The fourteen trace elements of As,Ca,Mg,Al,Mn,Sr,Ba,Se,Ni,Cd,Cu,Zn,Mo and Pb in the solution were determined by ICP-AES.The ICP-AES result was proved to be reliable by adding standard recovery experiment to the process.Compared with the result of chemical experiment,this method was accurate,fast and convenient.
