| Abstract: | A method for the determination of arsenic species (As(Ⅲ), As(Ⅴ)) in Traditional Chinese Patent Medicine by hydride generation-atomic fluorescence spectrometry (HG-AFS) using separation with exchange resin column has been described. The influence of experimental conditions on the fluorescence intensity, the reduction of arsenic and others were investigated and optimized. The detection limit arsenic compounds which convert from arsenic species to arsine (AsH 3) was 84.9 ng/L. The proposed method was successfully applied to the determination of As(Ⅲ)and As(Ⅴ) in Traditional Chinese Patent Medicine with a recovery of 90.8%～110.2%. |
