摘要

目的:建立氢化物发生-原子荧光光谱法测定锁阳药材中有害元素汞、砷的定量检测方法。方法:采用高氯酸-硝酸消解

原子荧光光谱法测定。结果:汞在0.1～0.5 ng·mL-1线性关系良好

回归方程Y=3.54×102X+9.54

r=0.999 7

最低检出限为0.022 ng·mL-1;砷在1.0～10.0 ng·mL-1线性关系良好

回归方程Y=1.65×102X-3.89

Abstract

Objective: To establish a method for quantitative determination of mercury and arsenic in Cynomorium songaricum by using intermittent-flow-hydride generation atomic fluorescence spectrometry（HG-AFS）.Method: The method of determination was set up by atomic fluorescece spectrometry method after digesting by perchloric acid combining nitric acid.Result: Mercury was linear in the rang of 0.1-0.5 ng·mL-1

the linear function was Y = 3.54 × 102X + 9.54

r = 0.999 7

the detection limits of mercury was 0.022 ng·mL-1.Arsenic was linear in the rang of 1.0-10.0 ng.mL-1

the linear function was Y = 1.65 × 102X-3.89

r = 0.999 9

the detection limits of arsenic was 0.151 ng.mL-1.Conclusion:This method was simple and quick

the results wereaccurate and reliable for quantitative determination of mercury and arsenic in Cynomorium songaricum.
