Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0023] Such as figure 1 Shown, the specific structure of soil mercury residue detection equipment of the present invention comprises:

[0024] Reaction module 1, mixed reaction pipeline 5, argon carrier gas pipeline 3, hydrochloric acid pipeline 2 and sodium borohydride pipeline 4;

[0025] Among them, the reaction module is equipped with a cross-flow valve made of Teflon material, and the argon carrier gas pipeline, hydrochloric acid pipeline and sodium borohydride pipeline are used as input pipelines to connect with the reaction module through the cross-flow valve, and the mixed reaction pipeline is used as the output. The pipeline is connected with the reaction module through a cross-flow valve.

[0026] In the embodiment of the present invention, the mixing reaction pipeline, the argon car...

Abstract

The invention relates to the technical field of chemical analysis, and particularly relates to a soil mercury residue detection device. The device includes a reaction module, a mixing reaction pipeline, an argon carrier gas pipeline, a hydrochloric acid pipeline and a sodium borohydride pipeline. The reaction module is provided with Teflon cross valves. The argon carrier gas pipeline, the hydrochloric acid pipeline and the sodium borohydride pipeline, as feeding pipelines, are connected to the reaction module through the cross valves. The mixing reaction pipeline as an output pipeline is connected to the reaction module through the cross valve. Through improvement in components as a whole, influence of mercury residues is reduced, and the mercury analysis accuracy, precision and the like are greatly improved.

Description

technical field [0001] The invention relates to the technical field of chemical analysis, in particular to a soil mercury residue detection device. Background technique [0002] Mercury has a corrosive effect on the digestive tract and damages the kidneys and capillaries. Acute poisoning is mostly caused by mistaken ingestion of mercury liter, which has symptoms caused by digestive tract corrosion. After absorption, kidney damage will result in urinary retention and capillary damage, resulting in plasma loss and even shock; in addition, mercury can interact with respiratory enzymes of pathogenic microorganisms. The combination of sulfhydryl groups inhibits its vitality, and finally suffocates it to death. [0003] Mercury is a naturally occurring element that can be found in air, water and soil. Mercury is a highly toxic and non-essential element that widely exists in various environmental media and food chains (especially fish), and its traces are all over the world. Mercu...
