Study on Primary Elemental Speciation Analysis and Extracting Characteristics of Trollius Chinensis by ICP-AES

The eight elements Mn,As,Pb,Cr,Mg,Fe,Cu,Zn of trollius tea were extracted based on traditional analytical flow chart program,and extracting solution of trollius tea was separated into water-soluble state and suspension state by micro porous filtering film.The primary speciation of trace elements were determined by inductively coupled plasma atomic emission spectrometry(ICP-AES).The extractive rates of the elements were in the range of 17.2%—72.3%.The ratio of water-soluble state in aqueous solution of Trollius tea was in the range of 67.4%—98.6%.
