摘要
采用微波消解样品，氢化物原子吸收法测定砷含量。方法检出限为0．036μg／kg，变异系数RSD=5．48％，回收率为90％～101％。该方法简单快速，灵敏度高，可作为药用真菌巨大口蘑中微量砷的测定方法。
Hydride generation atomic absorption spectrometry was used to determine arsenic by microwave digesting sample. The detection limit of the method was 0.036μg/kg, 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 Tricholoma giganteum.
