建立了一种通过原子荧光光谱测定糯米中汞含量的检测方法。采用硝酸/双氧水体系对样品进行微波消解预处理,利用原子荧光光谱法测定糯米中的痕量汞。方法加标回收率在98.67%—103.33%之间,相对标准偏差小于4.57%。该方法简便快速、准确灵敏,适用于糯米中痕量汞的测定。 A method for the determination of mercury in glutinous rice by atomic fluorescence spectrometry was established. The samples were subjected to microwave digestion pretreatment with nitric acid / hydrogen peroxide system and the trace mercury in glutinous rice was determined by atomic fluorescence spectrometry. The recoveries of the methods were 98.67% -103.33% with relative standard deviations less than 4.57%. The method is simple and rapid, accurate and sensitive, suitable for the determination of trace mercury in glutinous rice.
