Abstract

The amounts of K,Ca,Mg,Mn,Fe and Zn were determined in lotus leaves by flame atomic absorption spectrometry.The results indicate the contents of K and Ca are relatively high,and the contents of trace elemens of Mn,Fe and Zn decrease in turn.The analytic method offers satisfactory recovery(between 97% and 103.5%) and relative variation coefficient data(between 0.70% and 3.51%).
