There are many sample preparation methods for heavy metal detection of soil samples, but each has its advantages and disadvantages. Based on the above two pretreatment methods, the detection limit, precision, accuracy and actual soil sample measurement value of mercury detection in soil by atomic fluorescence were compared with atomic fluorescence, and the results showed that the automatic digestion and pretreatment system (DEENA) could digest soil samples to meet the requirements of GB/T 22105.1-2008 standard. Moreover, there was no significant difference between the two digestion methods on the detection results of mercury in soil, and the automatic digestion and preparation system (DEENA) was convenient, operable and highly automated, which was more advantageous for sample digestion.
