Abstract

The invention discloses a soil breakage type sampling device for gaseous mercury in soil. The soil breakage type sampling device comprises a manual gas extraction pump. A metal wire tube is communicated with an end of a first silicone tube, a second silicone tube is communicated with an end of the metal wire tube, a dust filter is mounted on the second silicone tube, a hollow shaft is communicatedwith an end of the second silicone tube, a slide sleeve slidably sleeves the hollow shaft, a cover is mounted on the slide sleeve, a soil breaking mechanism is mounted on the lower portion of the hollow shaft and comprises a sleeve, the sleeve slidably sleeves the hollow shaft, a drill bit portion is fixedly connected with the lower end of the hollow shaft, a pressing sleeve slidably sleeves thehollow shaft, and a sampling hole is formed in a side of the lower end of the hollow shaft. The soil breakage type sampling device has the advantages that users can acquire gas in the soil without taking out drill bits during sampling, accordingly, the problem of inaccurate sample acquisition due to the fact that gas in air flow into gas in existing soil and is mixed with the gas in the existing soil can be solved, and the gaseous mercury can be conveniently and quickly sampled by the soil breakage type sampling device during sampling.

Description

technical field [0001] The invention belongs to the technical field of gas mercury detection, and in particular relates to a soil-breaking type soil gas mercury sampling device. Background technique [0002] With the rapid development of modern industry, the problem of mercury pollution is becoming more and more serious. Atmospheric mercury and its biogeochemical cycle research has gradually become one of the hotspots in mercury pollution research. Atmospheric mercury can enter the soil through dry and wet deposition, and most of the mercury in the soil stays in the soil in various forms through complex physical and chemical reactions, and part of it is absorbed by plants. A small part is released into the atmosphere in the form of gaseous mercury under certain conditions, causing pollution. Therefore, the detection of mercury content in soil is particularly important. [0003] Determination of soil mercury refers to the pretreatment methods of samples when measuring merc...
