Problems solved by technology

The advantage of this device is that it can quickly enrich and concentrate trace organic matter in a large volume of water in the field, but it is necessary to bring the enriched metal column back to the laboratory, dry it with nitrogen and heat it for desorption, so that the organic matter enters the analyzer for determination. The function of automatic sampling after enrichment cannot be realized
The invention patent with the notification number CN101726437A discloses an online enrichment system for organic matter in water body, which can realize the sampling, enrichment, elution, online concentration and automatic sampling of organic matter in water body, but the enrichment column used in the system The filler is a solid phase, which is mainly used in combination with a liquid chromatograph, and petroleum pollutants need to be liquid-liquid extracted, enriched, and then measured by an infrared spectrometer or a fluorescence spectrometer. Therefore, this device is not suitable for online enrichment of petroleum pollutants. set device

Abstract

The invention discloses a water petroleum pollutant on-line enrichment device. The water petroleum pollutant on-line enrichment device has functions of automatic sampling, extraction and waste liquid classification and can avoid result errors caused by artificial operation. The water petroleum pollutant on-line enrichment device can realize continuous measurement of petroleum pollutants, can improve system extraction efficiency by cycling extraction, can eliminate the influences produced by common ions and humic acid in water on petroleum measurement, and can improve a detection precision. The water petroleum pollutant on-line enrichment device can realize automatic classification of a waste liquid and recycle of an extractant, and avoid secondary pollution on the environment.

Description

technical field [0001] The invention relates to a water body pollutant enrichment device, in particular to an online water body oil pollutant enrichment device. Background technique [0002] Petroleum pollutants contain carcinogenic polycyclic aromatic hydrocarbons. Although their content is very low, these carcinogens can endanger the human body directly or through the food chain when drinking water polluted by petroleum or eating polluted aquatic products. health and safety. At present, when the water environment is polluted by petroleum, a large number of water samples are generally collected and brought back to the laboratory for extraction and analysis and testing. Manual sampling is time-consuming and laborious, and the enrichment process is cumbersome. The extraction agent used is easily inhaled by the experimenter. Seriously endanger your health. In order to facilitate the routine monitoring of oil pollutants in water bodies, online oil monitors have developed rapi...
