摘　　要：采用微波消解处理样品,利用原子荧光法对刺五加系列产品中的砷和锑进行同时测定.确定了微波消解工作条件为：在1.0 MPa压力下消解3 min,在1.5 MPa压力下消解5 min,在2.0 MPa压力下消解2 min.在最佳工作条件下,砷和锑的质量浓度与荧光强度呈现良好的线性关系.砷的线性回归方程为IF=73.480X-5.810,锑的线性回归方程为IF=105.010X-0.353 3,线性范围均为0~100ng/mL.并选用标准物质人发对测定方法的准确度进行验证,结果表明,该方法简便灵敏、快速准确.A method for simultaneous determination of arsenic and antimony in series of acanthopanax senticosus harms products using atomic fluorescence spectrometry with microwave digestion is developed.The optimum microwave digestion conditions are： under pressure of 1.0 MPa,digestion time is 3 min,under pressure of 1.5 MPa,digestion time is 5 min,and under pressure of 2.0 MPa,digestion time is 2 min.Under the optimized experimental conditions,the concentration of arsenic and antimony show a linear relationship with the fluorescence intensity.The linear equation of arsenic is IF=73.480X-5.810,the linear equation of antimony is IF=105.010X-0.353 3,and the linear range for arsenic and antimony are 0～100 ng/mL.The method for accuracy and precision using the standard reference substance of hair is checked,and proved to be sensitive,simple and rapid with satisfactory results.
