| Abstract: | In the paper,a microwave digestion-atomic fluorescence spectrometer method for rapidly determining the mercury and arsenic in food was established.By optimizing the conditions(i.e.microwave digestion pre-treatment),the detection limits of mercury and arsenic were 0.023μg/L and 0.119μg/L,respectively.The relative standard deviations of sample determination(RSD)of mercury and arsenic were 6.2% and 3.3%,respectively.The recovery rate of samples for mercury and arsenic were 96.0%-105.0% and 95.9%-102.5%,respectively.The testing results with standard material met the requirements.This method was simple,rapid and sensitive,and could meet the testing requirements of food. |
