Description
Technical field
The present invention relates to pollutant Sampling techniques field, particularly relate to a kind of passive semi-volatile atmosphere organic pollutant sampling apparatus.
Background technology
The concentration of half volatile organic contaminant is very low in the atmospheric environment, conventional active sampling apparatus is by a large amount of gaseous samples of air pump collection, after gathering-device concentrates, carry out assay determination, need power resources, make sampled point on the installation position of space, be subjected to the restriction of objective condition.Passive sampling apparatus is based on the molecular diffusion principle, select suitable absorbing medium, be exposed to atmospheric environment and measure test substance content in the absorbing medium after a period of time, the sampling analysis of mating part active simultaneously result determines the sampling efficiency of passive sampling apparatus, obtains the concentration information of test substance in the environment.The semi-permeable diaphragm sampling apparatus once was widely used in the passive collection of pollutant in the water body, after be applied to (Jimmie D.Petty in the air passive sampling, James N.Huckins, James L.Zajicek, Application of semipermeable membrane devices (SPMDs) aspassive air samplers.Chemosphere, 1993 (27): 1609-1624).Shoeib adopts isocyanurate foam (PUF) material as absorbing medium (Shoeib, M. in the passive sampling apparatus comparative studies; Harner, T., Characterization and comparison of three passiveair samplers for persistent organic pollutants, Environ.Sci.Technol.2002 (36): 4142-4151), develop the PUF passive sampling apparatus.Above-mentioned two kinds of passive sampling apparatus have been widely used in atmospheric surveillance and the related science research.
Above-mentioned gaseous state half volatile organic contaminant passive sampling apparatus is an absorbing medium with olein and polyurethane foamed material respectively, be placed on and carry out the organic passive collection of atmospheric half volatile in thermometer screen or other the semiclosed devices, sampling finishes the back absorbing medium is extracted, concentrates (carrying out separation and purification in case of necessity), analyzes the content of half volatile organic compounds in the absorbing medium.Carry out the active sampling of part typical case sampling point in the time of passive sampling, obtain these sampling point gaseous state half volatile organic contaminant concentration informations, in conjunction with the passive sampling sampling efficiency of calculating sampling device as a result, calculate other sampling point atmospheric half volatile organic contaminant concentration in view of the above.
Above-mentioned passive sampling technology is all at the gaseous component of semi-volatile organic matter, and outside this compounds exists divided by gaseous form in atmosphere, part also can combine with particle in the atmosphere, especially wherein molecular weight is bigger, the component that volatility is more weak, most of form with the particle combined state is present in the atmosphere, and toxicity often is better than the component of small-molecular weight, high volatility, is the object that more merits attention in health and the exposure research.Above-mentioned sampling apparatus can not collect this component, though semi-permeable diaphragm or PUF surface can capture the small quantities of particles thing, but owing to do not have clear and definite differentiation with gaseous component, randomness is strong, poor reproducibility, can't obtain the concentration information of particle combined state half volatile organic contaminant in the atmosphere in view of the above, and the result of calculation of gaseous component is had certain interference effect.Atmosphere particulate matter sampler makes the airborne particle packing of certain volume on the filter medium (as filter membrane) of filtrator by the physical filtering effect, by filter medium accurately weighed and chemical analysis the mass concentration information of each component in the analysing particulates thing.Micropore uniform deposition formula collision sampling thief is (as MOUDI-100/110, NanoMOUDI-115, FA-3 etc.) aerosol sample of also gradable collection different-grain diameter scope is analyzed the mass concentration information that obtains each component in the different-grain diameter particle by the later experiments chamber.But, above-mentioned particle sampler all needs power resources, makes to be very limited on sampling point is laid.In recent years portable sampling of aerosol instrument of Chu Xianing and gasoloid passive sampling apparatus can provide the information of aerosol concentration and size distribution in the air, but because sampling quantity is little, can't carries out post analysis, thereby obtain the concentration information of target compound in the particle.
