摘　　要：本文以琼脂溶液作悬浮剂,超声波搅拌,自动进样器进样,氢化物发生原子荧光分光光度仪测定了米粉样品中的痕量汞,方法线性关系良好,相关系数R2=0.9998,RSD(n=7)在1.36-4.15之间,回收率在98.7-102.0%之间,此方法测定简单,快速、回收率、准确度高,结果准确可靠。In this paper, the trace mercury in the sample was determined by using the agar solution as a suspending agent, ultrasonic stirring, automatic sample injection, hydride generation atomic fluorescence spectrometry. The results showed that： correlation coefficient R^2 was 0.9998, RSD（n=7） was 1.36-4.15%, recovery rate was 98.7-102.0%. This method can measure the content of mercury in ground rice samples quickly and easily.
