Arsenic in Chinese herbs was determined by Hydride Generation Atomic Absorption Spectrometry (HGAAS). The method was simple and fast, and could be applied to great amount of samples. The detection limit of arsenic was 0.020 mg/kg (dry weight). The recovery and relative standard deviation (RSD) of all samples were 81.5%-125% and 6.2-18.4% respectively. The determined arsenic content of GBW08501 SRM was 82.4%-114.7% of the certified value, and the RSD was 12.6%.
采用氢化物发生原子吸收光谱法(HGAAS)测定中药中的砷。该方法简便快速,可应用于大量样品。砷的检出限为0.020 mg/kg(干重)。所有样品的回收率和相对标准偏差(RSD)分别为81.5%-125%和6.2%-18.4%。GBW08501标准参考物质的砷测定值为认定值的82.4%-114.7%,相对标准偏差为12.6%。
