Open publisher page 0 citations

Abstract

Hydride generation atomic absorption spectrometry was used to determine arsenic with microwave digesting sample.The detection limit of the method was 0.036 μg/Kg,RSD=5.48%,the recovery was in the range of 90%～101%.Because this method is simple,rapid and very sensitive,it can be applied to the determination of trace arsenic in Morchella.
