Problems solved by technology

The principle of this kind of gold film sensor is simple, the gold film can be reused, and it is not easy to be affected by environmental changes when measuring mercury relative to the principle of spectroscopy. However, the sensitivity and response speed of the current gold film sensor cannot meet the detection requirements, and the amount of mercury adsorbed reaches 10 -7 It tends to be saturated at the g level, resulting in a larger measurement error

Embodiment

[0031] EXAMPLIC: Rate type trace mercury sensor of this embodiment, such as figure 1 As shown, including the housing formed by the base 1 and the top cover 2 and the grid plate 3 mounted in the housing, the housing is square casing, and the polytetrafluoroethylene material, the top cover, and the base are 3 mm respectively. The intake port 4 and the outlet 5, there is a cavity on the base, and the inner wall of the base is a lap shoulder 6, and the grid is mounted on the shoulder of the base, and the top cover has a cavity corresponding to the cavity on the base. After the cavity, the top cover and the base are fastened to form an air chamber within the housing, and the grid is separated into the upper and lower cavities, the left and right edges of the base, respectively, have a horizontal terminal 7, respectively. At both ends of the terminals, both ends are located within the housing, outside. Such as figure 2 As shown, the grid plate has a plurality of mutually parallel strip-...

Abstract

The present invention involves a grid board seacterioscous mercury sensor and its preparation method.The grid plate seams are mercury sensors include the shells with air intakes and air outlets and grille plates set in the shell.The two electrodes connected to it, the mercury induction film layer includes the silver -gold composite nanoparticles, gold nano -thin film layer, gold chromium composite film layer, and chromium nano -thin film layer from top to bottom.Two wiring terminals connected to two electrodes.The preparation method of the signs of mercury sensor is: prepare mercury induction film layer on the grid board; two electrodes are formed by corrosion of the light engraving; put the grid plate into the base;Combine; cover the top cover on the base and seal.The present invention greatly improves the sensitivity and response speed of the sensor, strong induction signals, wide measurement range, and is not vulnerable to environmental impact.

Description

Technical field [0001] The present invention relates to a sensor that detects the mercury concentration in the gas, and more particularly to a grid plate trace mercury sensor and a preparation method thereof. Background technique [0002] The large-scale production of industrialization has led to about 24 million tons of mercury per year to be placed in the atmosphere, which in turn into the food chain through the soil, ocean. Entering the human mercury through methymp in the form of methyl mercury, thereby causing irreversible damage to the nervous system, brain and fetus. According to reports, the human body is exposed to the mercury steam of 0.1 to 0.2 ppm, and only a few hours will lead to chemical bronchitis, chemical pneumonia and pulmonary fibrosis, which have great harm to the human body and creatures. Therefore, the mercury content in the detection environment is very important. Measuring environmental mercury pollution, detection limit requirements reach 10 -9 g magnitu...
