Determination of Fe,Mn,Cu and Zn Elements in Corn by Flame Atomic Absorption Spectrometry

LI Guo-lan

Abstract

With HNO3～HClO4(4+1) wet indesgition method to pretreat samples,the contents of four elements Fe,Mn,Cu,Zn in Corn had been determinated by flame atomic absorption spectrometry.And the recovery rate of 97%～99% for Fe,95%～100% for Mn,95%～103% for Cu,100%～104% for Zn were obtained.The average rate was 95%～104%.RSD was 0.1%～0.9%.It was shown that the method was reliable for the test of precision and accuracy.
