| Abstract: | [Objective] The aim was to explore the rapid determination method of mercury in plants.[Method] With pure nitric acid as the medium,the content of mercury was determined by hydride atomic fluorescence spectrometry when the samples were digested by microwave.And the best microwave digestion conditions were explored.[Result] The results showed that the relative standard deviations of this method were less than 1.03% except standard value of corn was recommended value,and the lowest detection limit was 0.009 μg/kg.[Conclusion] Microwave digestion method was simple,rapid,accurate and high sensitivity,and suitable for the batch and rapid determination of mercury in plants. |
