Abstract
The utility model discloses a simple device used for sampling of organic pollutant in the atmospheric deposition. The simple device comprises a quartz filter membrane and PUF sampling foam, and is characterized in that a sampling device consists of an upper part and a lower part which are communicated and connected with each other; the upper part is a Buchner funnel; the lower part is a glass cylinder; the bottom of the glass cylinder is communicated with the atmosphere; the quartz filter membrane is arranged at the bottom of the Buchner funnel; and the PUF sampling foam is arranged in the glass cylinder. The device is wholly supported by a triangular wood support. The device is not provided with an air pump, the structure is simple, the power supply is not needed, and the passive samplingis carried out by means of atmospheric transmission and rainfall. The dry/wet particle phase collection and solution phase pollution collection to be analyzed and detected can be obtained by taking out a crossed glass strip 2 and loosening gauze 8. The simple device is applicable to be arranged at the sampling points with wide range, and can meet the sampling purpose of remote transmission research and monitoring of the organic pollutant in the atmospheric deposition.
Description
Technical field
The utility model is a kind of atmosphere environment supervision instrument, and particularly a kind of easy device that is used for the sampling of atmospheric sedimentation organic contaminant is applicable to the sampling of dried wet granulation of atmosphere and solution organic contaminant.
Background technology
Persistence organic pollutant in the atmosphere (POPs) can enter in the surrounding mediums such as surface soil, water body and vegetation by the atmosphere dried wet deposition effect.For away from pollution source, clean relatively area, atmospheric pollution transmission and dried wet deposition especially in its ground surface environment polluter main come source procedure.The atmosphere dried wet deposition effect of half volatile POPs shows as particle dried wet deposition and gaseous state dried wet deposition dual mode.
Palycyclic aromatic (PAHs) is found the earliest carcinogenic organic compound, has widely to distribute in environment.The persistent pollutant regional evaluation plan of carrying out in the recent period of organizing in concert by United Nations Environment Programme (UNEP) (UNEP) and Global Environment Facility (GEF), in the Central Asia that comprises China and Northeast Asia country (VII workspace, totally 11 countries and regions) in the persistent pollutant that filters out, PAHs ranks the 4th.Therefore, select PAHs to carry out atmosphere dried wet deposition research and have representative preferably and important realistic meaning.
But the device that is fit to carry out the sampling of atmospheric sedimentation organic contaminant is not arranged as yet in the prior art.
Summary of the invention
The utility model purpose is to provide a kind of easy device that is used for the sampling of atmospheric sedimentation organic contaminant, need not power supply, can collect again and do wet granulation and solution organic contaminant, to adapt to open-air non-transformer and sampling use on a large scale, be applicable to the sampling of dried wet granulation of atmosphere and solution organic contaminant.
Scheme of the present utility model is, a kind of easy device that is used for the sampling of atmospheric sedimentation organic contaminant, has quartzy filter membrane and PUF sampling foam, it is characterized in that, this sampling apparatus is made of the connection of two parts up and down that interconnects, and top is divided into Buchner funnel, and the bottom is divided into glass cylinder, the glass cylinder bottom is communicated with atmosphere, and described quartzy filter membrane is arranged on the bottom of Buchner funnel; Described PUF sampling foam is arranged in the glass cylinder.
The prioritization scheme of above-mentioned easy device has:
1, the quartzy filter membrane of Buchner funnel bottom blocks fixing with the glass bar of right-angled intersection;
2, Buchner funnel and glass cylinder two parts are in aggregates by the silica gel adhesion;
3, described glass cylinder bottom is sealed by the cotton gauze;
4, wrap up with aluminium foil, the plastic foil that is coated with metal level or tinfoil outside the described glass cylinder;
5, device is whole by the triangular form stent support.
The utility model does not have the aspiration pump of common atmosphere pollution sampling apparatus, rely on the sampling of propagation in atmosphere and rainfall passive type, thereby need not power supply, the roomy bell mouth in top is convenient to collect pollutant, quartzy filter membrane on the funnel is collected and is done wet granulation, PUF sampling foam adsorbent solution phase organic contaminant in the glass cylinder of lower part, simple in structure, both be suitable for being installed near the sampled point of pollution source, be adapted to be mounted to the backwoodsman sampled point that lacks power supply again, can satisfy the sampling that the atmospheric sedimentation organic pollutant monitoring is a purpose.
