Detachable liquid-state binder-phase DGT (diffusive gradients in thin-films) shell for detecting soil

Abstract

The invention provides a detachable DGT casing for liquid state detection of soil, which includes a casing, a cover body and a handle; The holes are matched; the cover is provided with a second through hole; the right end of the housing is open, and a first sealing plate is provided around the opening of the right end of the housing, the end face of the handle is equal in size to the inner end face of the housing, and the upper surface of the first sealing plate is The distance from the end face of the housing is equal to the thickness of the handle; the handle is detachably connected to the first sealing plate. A detachable DGT shell for soil detection in a liquid state according to the present invention, by setting a detachable handle, on the one hand, the liquid state can be injected into the housing from the handle; on the other hand, the DGT device can be inserted into the housing by using the handle In the soil; the setting of grooves and protrusions ensures the overall airtightness of the device; the setting of the scale line can clearly record the depth inserted into the soil.

Description

technical field [0001] The invention belongs to the technical field of DGT, and in particular relates to a detachable DGT shell of a liquid binding phase for soil detection. Background technique [0002] After heavy metal ions enter the soil, a small amount can effectively affect the metabolic activity of soil microorganisms and become effective metals. Toxic pollutants such as heavy metals continue to accumulate in the bed. With the "saturation" of heavy metal ions in the matrix, the new heavy metal ions will It acts on the wetland microbial community in an effective form and severely inhibits denitrification. Although the total amount of heavy metals can be used as an important indicator of its toxic effects, the correlation between the total amount and its toxic effects on organisms is not significant. Therefore, researchers have been exploring a A monitoring method that can effectively reflect the toxic effects of heavy metals is used to replace the full assessment of he...
