微波消解-原子荧光光谱法测定宫瘤消片中的砷、镉

目的: 测定宫瘤消片中的砷、镉。 方法: 采用微波消解的制样方法,利用原子荧光光谱法测定了宫瘤消片中镉、砷微量元素的含量。 结果: 测得2种元素,标准曲线的r>0.9992,回收率为91.5%~97.8%,RSD<5%。 结论: 本法快速、准确且灵敏度高,为宫瘤消片中重金属含量测定提供了较好的方法,结果满意。

Objective: To develop a atomic fluorescence spectrometric method for the determination of heavy metals(As,Cd) in Gongliuxiao. Method: Sample were digested with microwave system,and the As,Gd were directly analyzed by atomic fluorescence spectrometric. Result: For the analyzed heavy metals,the correlative coefficient of the calibration curves was over 0.9992,the recovery was 91.5%-97.8%,RSD was less 5%. Conclusion: The method is convenient and highly sensitive.The method had been applied to the determination of trace heavy metals in traditional Chinese medicine with satisfactory results.
