Abstract

The approach of adapting microwave digestion to process samples,FAAS to determine trace elements manganese,zinc,copper,iron was discussed in the same system,including the amount of nitric acid,hydrogen peroxide and the length of time to digest,which affects the experiment,and the mutual interference of mananese,zinc,copper,iron in the same system.In selected conditions,the content of manganese,zinc,copper,iron respectively is:Mn 10.05 mg/kg,Zn 9.48 mg/kg,Cu 3.06 mg/kg,Fe 18.30 mg/kg,recovery of 96.8%～98.9%.
