Abstract
The invention discloses a water passive sampler of pollutants, which comprises a box body and an adsorption film arranged in the box body, wherein the box body comprises a box body frame and a box cover forming a closed box body together with the box body frame; a filter screen and a filter film are arranged in the box cover in sequence, and the upper side and the lower side of the filter film are respectively provided with a sieve plate. In the invention, the adsorption film is arranged in the box body, particulate matters can be filtered by the box cover provided with the filter screen and the filter film, and thus, active organisms are prevented from entering into the box body to adhere to the adsorption film; and the sieve plates arranged at the upper side and the lower side of the filter film can protect the filter film from being damaged under the impact of water stream. The sampler can effectively prevent the water environment in the box body from being polluted by outside particulate matters and microorganisms. The sampler can be applied to the field of water sampling of pollutants.
Description
Technical field
The present invention relates to a kind of pollutant water body sampler, particularly relate to a kind of pollutant water body Passive sampler.
Background technology
That persistence organic pollutant refers to is residual in the environment midium or long term, migration and the high toxicity hydrophobic organic accumulated in biosome, persistence organic pollutant in the environment is mainly composed and is stored in the sediment organic phase, and the natural waters such as rivers,lakes and seas preserve the carrier except conduct, the important gravitation of persistence organic pollutant migration is the important content of Research of Environmental Sciences and environmental monitoring so measure the concentration of persistence organic pollutant in the water body especially.
The water body environment organic contaminant method of sampling is divided into initiatively sampling and passive sampling two classes, passiveness sampling method comes enriched sample with the spe medium of high partition factor, need not additionaling power in the sampling process, be suitable for monitoring in the open air to be used, the passiveness sampling method of existing water pollutant mainly contains original position solid phase micro-extraction technique, Immunohistochemistry and low density polyethylene films abstraction technique.
The original position solid phase micro-extraction technique is take coating of high molecular polymer as adsorbent; use multi-hole copper tube and glass fibre membrane protection spe membrane and filtration of particulate matters, solid phase micro-extraction technique has the volume of water sample demand little, detects the low advantage of limiting the quantity of; but the extraction probe price is very expensive, and is very easily damaged.
Immunohistochemistry is that lipoid is sealed in the semi-permeable diaphragm, be enriched to the mode of biosome by water through biological membrane with similar organic compound, organic pollutants is extracted, measure after the counter-infiltration, but the lipoid that this kind detection method is used is expensive, thereby permeability biological and the particle meeting of adhesion reduction polyethylene film reduces sampling rate.
Later stage research finds that polyethylene film can adsorb object equally, so Immunohistochemistry develops into the low density polyethylene films abstraction technique, but can stick particle and microorganism in the water body in the exposed low density polyethylene films abstraction technique lowered in field environment, affect measurement result.
Summary of the invention
For addressing the above problem, the invention provides a kind of pollutant water body Passive sampler that can effectively avoid particle and microorganism in the water body.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of pollutant water body Passive sampler, comprise box body and be arranged at the interior adsorption film of described box body, box body comprises that the box body framework reaches the lid that forms airtight box body with the box body framework, is provided with successively screen pack and filtering membrane in the lid, and the up and down both sides of filtering membrane are equipped with sieve plate.
Be further used as the improvement of technical solution of the present invention, sieve plate is provided with the O-ring seal that can be embedded in the lid outward.
Be further used as the improvement of technical solution of the present invention, the both ends open of box body framework is equipped with lid, and lid is provided with some spring carrier arms, is provided with fastening spring between the corresponding spring carrier arm in box body framework two ends.
Be further used as the improvement of technical solution of the present invention, be provided with the support that supports adsorption film in the box body, support comprises the support base plate and is fixed in the pillar of the support base plate both sides some equidistant arrangements vertical with the support base plate that adsorption film is arranged in an intercolumniation wound in parallel.
Be further used as the improvement of technical solution of the present invention, screen pack and lid all adopt copper product, and filtering membrane is glass fiber filter, and sieve plate is the stainless steel sieve plate.
Beneficial effect of the present invention: this invention is arranged at the adsorption film of absorbability in the box body; carry out the filtration of particle by the lid that is provided with screen pack and filtering membrane; prevent that simultaneously microorganism from entering box body and attaching on the adsorption film; sieve plate is set in the up and down both sides of filtering membrane can protects the filtering membrane can be damaged under water impact, this sampling thief can effectively avoid water environment in the box body by extraneous particle and microbial contamination.
