| Abstract: | A method was established to determinate trace mercury in glutinous rice. A~ter a pretreatment with HNO3/H202 microwave digestion system, cold atomic fluorescence spectrometric method was used to determine trace mercury. The recovery rate of samples is 98. 67%-103.33%, RSD is less than 4.57%. This method is simple,rapid,sensitive and accurate. It can be used in trace mercury determination of glutinous rice. |
