RESUMEN
OBJECTIVE:To determine the contents of arsenum (As) and stibium (Sb) in Fmoes officinalis Ames by hydride generation-atomic fluorescence spectrometry.METHODS:The determination conditions were as follows:60 mA electric current and 300 V negative high voltage for As hollow cathode lamp;80 mA electric current and 300 V negative high voltage for Sb hollow cathode lamp,the height of atomizer was 8 mm,the flow rate of carrier gas was 400 mL?min-1;the flow rate of the shield gas was 1 000 mL?min-1,the atomizer temperature was 200 ℃.RESULTS:The linear ranges for both As and Sb were 0～100 ?g?L-1 (r=0.999 9),with detection limits at 0.03 ?g?L-1 and 0.08 ?g?L-1,respectively;The recovery rates were 97.4%～102.2% (RSD=1.86%) and 98.2%～102.6% (RSD=1.66%),respectively.CONCLUSION:The method is rapid,accurate and achieved ideal results in the determination of As and Sb in Fmoes officinalis Ame.
