| Abstract: | Objective：To establish the graphite furnace atomic absorption spectrometry（GFAAS） method for the determination of trace lead,cadmium and cupper in synthetic borneol.Methods：The detection wavelength was at 283.3 nm for lead,228.8 nm for cadmium and 324.7 nm for cupper,the lamp current was 2.0～3mA and the slit-width was 0.4 nm.Results：In the range of 0.0～40.0 ng/mL for lead,0.0～40.0 ng/mL for cadmium and 0~10 ng/mL for copper,the good linear relationship was revealed.The average recovery rates were 98.3%,98.0% and 97.3% respectively.Conclusion：This method is accurate and reproducible for determining the content of lead,cadmium and cupper in synthetic borneol. |
