In order to solve the technical matters that prior art exists, discovery is studied through inventor, organism is the important component part of atmospheric aerosol, account for 10% ~ 50% of particle total amount, in the chemical composition of particle fine particle, organism is one of species of enriching the most of content, has material impact to health, visibility and Global climate change.These effects depend on they self physics and chemistry character, as particle diameter, water-soluble and refractive index etc., and source, to transform and transmitting procedure.But the of a great variety and complex structure of the organic compound in particle, concentration level is low and physicochemical property difference large, makes people be familiar with particulate organic matter behavior in an atmosphere and effect becomes very difficult.Due to the restriction of analytical test means, until the 1950's just starts the research of particulate organic matter, enter the eighties to be developed rapidly, based on current GC-MS assay method and technical merit, researcher has identified hundreds of kind organic compound from air organic particulate matter, but these compounds only account for the 10%-40% of particulate organic matter quality altogether.In the fine particle chemical composition mass balance that Rogge obtains in the research of California, organism accounts for 15% of fine particle gross mass, and more than the 80 kind of organic compound detected accounts for 13% of total organic compound, only account for about 2% of fine particle quality, U/I part comprises humic acid, high relative molecular weight compound, senior property compound and unresolvable naphthenic hydrocarbon and branched paraffin potpourri (UCM).And this wherein some molecular structure that has of surperficial organic active substance and feature just.Aerosol Surface organic active substance, primarily of fatty acid and amphiphilic derivatives thereof or unitary, binary, polyprotonic acid or class humic substance composition, is mainly distributed in Fine Particles, is mainly the electronegative material of hydrophilic radical, i.e. anionic surface active substances.Its source comprises the coal smoke etc. that soil ulmin degraded, biomass combustion, sea spray and burning produce.Have the effects such as Interfacial Adsorption, solubilization, reduction solvent surface tension, therefore, surperficial organic active substance is at PM
2.5the existence on surface, to PM
2.5surface tension and the character of surface such as hydroscopicity there is material impact, thus material impact is produced to Global climate change, atmospheric environment and health.
For Fine Particles PM
2.5the limitation of middle organism determination method, the humic acid using GC-MS technology can not differentiate to the water soluble organic substance sample after process, high relative molecular weight compound, senior property compound and the material such as unresolvable naphthenic hydrocarbon and branched paraffin potpourri (UCM) (these are all the molecular structure that has of surperficial organic active substance and feature), sampling flow injection instruments quantitative test can identify existence and the mass concentration of surperficial organic active substance, for the organic chemistry composition of Atmospheric particulates and method establishment provide invention foundation.
The detection method of the Atmospheric particulates surface organic active substance that embodiment 1, the present embodiment provide, its principle is the automatic detection of mensuration anionic surface organic active substance is based on following reaction: in aqueous, methylene blue and anionic surface organic active substance react and generate blue salt, with the salt that chloroform extraction generates, extract is in 650nm colorimetric estimation absorbance.The material measured is MBAS (methylene blue active substance).By using alkalescence-and acid methylene blue solution removing interference.Also be, the process of ELIMINATION OF ITS INTERFERENCE is: anionic surface organic active substance, can form ionic complex with methylene blue kation, this ionic complex can by chloroform extraction, and the solubleness of methylene blue in chloroform not forming ionic complex is very little.Use chloroform to be extracted from the methylene blue of alkalescence by the ionic complex that anionic surfactant and methylene blue solution are formed, this step can remove the protein negative sense interference in environmental water sample.Use acid methylene blue solution reextraction chloroform phase again, with the interference thing removing other as inorganic anion (NO
3-, Cl
-deng), be dissolved in chloroform because the bond of these materials and methylene blue is more difficult.Finally, chloroform enters detecting device mutually, carries out colorimetric analysis at 650nm place.
Based on above-mentioned principle, shown in Figure 1, comprise following key step:
S11, by blue to sample and alkaline methylene base solution complexing.
Above-mentioned sample obtains in the following way, gathers fine particle (PM in surrounding air with quartz filter
2.5), use the Soluble Anions surface organic active substance in the ultrasonic extraction particle of deionized water, extract is through 0.45 μm of membrane filtration, and the SKALARSAN++ Continuous Flow Analysis instrument that filter liquor uses Holland to produce measures.
The salt generated after S12, the complexing of employing chloroform extraction.
S13, adopt acid methylene blue solution reextraction chloroform phase.
S14, mutually colorimetric analysis is carried out to described chloroform.
Adopt in specific implementation SKALARSan++ Flow Analyzer introduce in analytic process air bubble as sample room every and pipeline-cleaning.Adopt the method for continuous flow by the elastic pump tubes of peristaltic pump compression different inner diameters, to mix under certain condition, be separated chaff interference in reagent and sample in proportion suction line system, insulation reaction, above program all on-line carries out, adopt two abstraction technique to realize, extract and completed by glassy phase separation vessel.SKALARSan++ Flow Analyzer conditional parameter can be set as: sample injection time: 120sec, flush time 140sec, air time 1sec, sampling volume 1.0mL, system stability time 30min.
Shown in Figure 2, comprise following flow process:
S21, blue to sample and alkaline methylene base solution is inserted SKALARSAN++ Continuous Flow Analysis instrument carry out complexing.
S22, adopt chloroform extraction complexing after the salt that generates, namely extract the ionic complex that anionic surfactant and methylene blue solution are formed.Concrete extraction adopts phase separator 1 to complete, and the aqueous phase obtained is discharged as waste liquid, and the organic phase obtained enters subsequent step.
S23, adopt acid methylene blue solution reextraction organic phase, concrete reextraction adopts phase separator 2 to complete, and the aqueous phase obtained is discharged as waste liquid, and the organic phase obtained enters subsequent step.
S24, SKALARSAN++ Continuous Flow Analysis instrument carries out colorimetric analysis to organic phase.
Survey absorbance after S25, colour developing, take peak height as ordinate, contents of anionic surface active substances (mg/L) is horizontal ordinate, drawing standard curve, and data are transferred to computing machine and carry out Treatment Analysis result.And discharge organic liquid waste.
Adopt the present embodiment, utilize flow injection analyzer small size sample introduction, online pair extracts, analysis speed is fast, reduce the absorption of objectionable impurities methenyl choloride, method detection limit is low, has the advantages such as good preci-sion and accuracy, illustrates that method of testing is effectively feasible.Be applicable to air PM
