Abstract

The invention discloses a sulphur dioxide detecting system and a sulphur dioxide detecting method. The system disclosed by the invention comprises a liquid path unit, a gas path unit and a detecting unit, wherein the liquid path unit is used for absorbing and enriching sulphur dioxide gas in atmosphere through an absorbing liquid to react to generate a sulphite solution; mixing the sulphite solution and a detecting reagent, and feeding the mixed solution into the detecting unit; the gas path unit is used for purifying air and feeding the purified air into the detecting unit; the detecting unitis used for detecting a light emitting signal and converting a detecting result into a sulphur dioxide concentration numerical value when the mixed solution of the sulphite solution and the detectingreagent is in contact with the purified air to perform a gas-liquid phase chemiluminescence reaction. The method disclosed by the invention corresponds to the system. According to the system and themethod, the absorption and enrichment as well as the subsequent high-sensitivity detection of the sulphur dioxide in the atmosphere are realized under the premise of ensuring real-time continuous detection; the system and the method have the advantages of simple device, high detecting sensitivity, few interference factors and the like.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a sulfur dioxide detection system and detection method. Background technique [0002] Sulfur dioxide is one of the main pollutants in the atmosphere, and it is also one of the key objects of atmospheric monitoring. Sulfur dioxide is an important source of atmospheric acid rain, which has adverse effects on the system and organization of the human body, and can also cause serious harm to plants. The detection of atmospheric sulfur dioxide is helpful to determine the degree of sulfur dioxide pollution and guide the development of sulfur dioxide pollution control work. [0003] At present, for the detection of sulfur dioxide, there are many detection methods, such as plant monitoring method, electrochemical method, chemical method, optical method and so on. In the field of atmospheric monitoring, photochemistry is commonly used, such as ultraviolet abs...
