The reaction kettle comprises a kettle body, a kettle cover and an air inlet pipe; the kettle cover is matched and connected with the kettle body; kettle cover is provided with an air inlet hole; the air inlet pipe is arranged in the kettle body; the first end of the air inlet pipe communicates with the air inlet hole; the second end of the air inlet pipe extends to the lower part of the kettle body; and the kettle cover is providedwith an air outlet hole and a liquid injection opening, wherein the kettle body, the kettle cover and the air inlet pipe are made of polytetrafluoroethylene. The invention provides the reaction kettlefor reducing mercury residues.

Description

technical field [0001] The invention relates to the technical field of mercury trace analysis, in particular to a reaction kettle and a mercury trapping structure for trace mercury analysis. Background technique [0002] At present, the determination of trace mercury compounds in environmental media generally uses the digestion method to oxidize the mercury compounds into divalent mercury ions, and then use the reducing agent to reduce the divalent mercury ions into gaseous mercury in the reactor, and use the gold sand collecting tube to pass through the gaseous mercury Mercury forms gold amalgam to trap and fix gaseous mercury, and finally use atomic fluorescence or atomic absorption instruments to measure the concentration of mercury desorbed by thermal desorption of gold amalgam adsorption tube. [0003] Existing reaction bottles generally use ordinary glass bottles or quartz bottles, but when exploring new methods for the determination of mercury samples, especially when...
