摘要
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.
