Open publisher page 0 citations

Abstract

Hydride generation atomic Absorption spectrometry was used to determine arsenic by microwave digesting sample.The detection limit of the method was 0.036μg·kg-1,RSD=5.48%,the recovery was in the range of 90%~101%.The method is simple,rapid and with high sensitivity,and can be applied for the determination of trace amounts arsenic in Cardiocrinum giganteum.
