Description

Soil organic pollutant is fluorescence collection device for in situ monitoring analysis
Technical Field
The invention relates to the field of environmental detection, in particular to a fluorescence collecting device for in-situ monitoring and analysis of soil organic pollutants.
Background
Polycyclic aromatic hydrocarbon toxic organic substances PAHs are typical pollutants of soil in China, and the pollution degree of the PAHs is second to that of heavy metals. PAHs are easy to be adsorbed by soil particles for long-term accumulation to form persistent environmental pollutants, and are subjected to carcinogenic, teratogenic, genogenic mutation and other hazards to a human body through migration and enrichment of food chains, and are listed as priority pollutants in the soil pollution risk control standard of soil environmental quality agricultural land. The soil pollution control action plan issued by the state institute clearly provides that organic pollutants such as polycyclic aromatic hydrocarbons and petroleum hydrocarbons in soil are monitored in a key mode, a soil environment monitoring technical system is perfected, and the county and county full coverage of soil environment quality monitoring points is achieved. Therefore, the rapid and effective monitoring of soil PAHs pollution is the foundation of soil pollution investigation, control, treatment and restoration, and the building of a soil quality monitoring network is the premise of mastering the soil pollution condition and developing the soil treatment and restoration work.
At present, the soil PAHs detection is mainly based on laboratory analysis and is assisted by on-site rapid detection. In the laboratory analysis, PAHs multi-component detection is realized by field sampling and laboratory gas-liquid chromatography, mass spectrum and the like, but the operation is complex, the detection efficiency is low, and the rapid in-situ detection of the PAHs in the soil is difficult to realize.
The soil PAHs can be rapidly detected on site by portable gas chromatography-mass spectrometry, infrared spectrometry and the like. The portable gas chromatography-mass spectrometry measurement system can realize field analysis of the PAHs by combining purging and trapping, but the field application range is limited by the problems of poor separation degree and accuracy, high field carrier gas supply, auxiliary equipment operation, high power consumption and the like. The infrared reflection spectrum can be used for quantitative analysis of organic pollution of hydrocarbons such as soil diesel oil, gasoline and the like, but PAHs molecular functional group vibration modes are weak and wide bands are overlapped, so that the infrared reflection spectrum cannot be used for multi-component synchronous detection of PAHs.
Therefore, in order to timely and comprehensively master the soil PAHs pollution condition, research and development of a technology for rapidly measuring the total organic pollution amount and the content of each component of the soil PAHs in situ is urgently needed.
