Determination and Analysis of the Ca,Fe,Zn,Cu,Pb In eucommia leaves in Ankang

LU Xu-hui

Abstract

After dispersing the power of eucommia leaves with HNO3:HClO4=4:1,then the copper,zine,iron,calcium,lead contents of eucommia leaves can be determined by Flame Absorption Spectrometry.The relative standard deviation(RSD) is smaller than 0.3779% and the recoveries obtained are 95～105%.The results obtained are satisfactory.
