Technical field
The present invention relates to a kind of passive sampling apparatus for gathering polar contaminants in water body.
Background technology
Efficiency can be increased substantially by shortening the sampling time, and therefore, the time saving and energy saving method of sampling is just gradually by people
Pay close attention to.Traditional method of sampling is mostly automatic sampling or sampling manually, although method is simple, can comparatively fast predict result；But
That can only determine that concentration is larger or the pollutant of monitoring method high sensitivity, and draw be mean concentration in very short time or
Person's instantaneous concentration, it is not accurate enough.This equipment uses passive sampling, will not be by time, burst equivalent to a kind of in-situ enrichment technology
The limitation of the factors such as event, while actual sample can also be avoided to be transferred back in lab process and changed, relatively actively sample
Technology is highly efficient cheap.
In the technology of current collection Organic substance in water, enrichment phase is generally macromolecule organic phase, and polarity is weaker, extracter
Reason is based on " similar to mix ", the enrichments for being directed to hydrophobic organic compound more.And for being enriched with the technology of Hydrophilic polar materials
It is less, need to collect a large amount of water bodys during sampling into being enriched with again behind laboratory, and applicable pellicle is few, by environmental factor
Influence it is big, the rate of recovery is relatively low and unstable, costly, and program is complicated.The present apparatus can realize that original place samples, Simple portable,
And efficiently concentrating is carried out to Hydrophilic polar materials in water body using recoverable polar organic matter adsorbed film, improve for richness
Collect the deficiency of Hydrophilic polar pollutant technology.
The content of the invention

In the use of the present invention, passive sampling apparatus is goed deep into water, water level control bar is rotated, with regulation to the depth of water to be surveyed
Length, opening control valve opens flap A and flap B, and current will be entered by flap A position；Alarm for flow-rate is surveyed
Constant current speed；Alarm for flow-rate indicator lamp is observed, if indicator lamp lights, shows that water velocity is relatively low, needs the longer sampling time, this
When, if wanting to accelerate sample rate, it is possible to open flow control valve, that is, opening water pump makes water sample enter in device；Current pass through
Screen pack A carries out simple filtration, removes the impurity such as sandstone, particulate matter；Impurity is collected by waste tank, can periodically remove cleaning；
The water obtained after filtering enters second space along device, passes through recoverable pole under the drive of the gear B of passive sampling apparatus
Property organic matter adsorbed film carry out organic matter in adsorbed water body, by certain adsorption time, go out outflow from screen pack B, it is final logical
The position for crossing flap B is discharged to the outside of passive sampling apparatus.Recoverable polar organic matter adsorbed film is under the drive of gear A
Into polyester ammonia bubble chamber, it is collected；At the end of sampling, first device will be taken out the water surface, after water emptying, then by flow velocity control
Valve processed is closed, and finally closes flap control valve；Sampling terminate after, passive sampling apparatus is cleaned and freeze-drying at
Reason, Instrumental Analysis is carried out after collection sample is gone into concentration in advance；Screen pack A and screen pack B will be according to the use feelings of device
Condition is changed, to ensure effectively filtering；Recoverable polar organic matter adsorbed film will be carried out more according to the service condition of device
Change, to ensure efficiently sampling；After sampling terminates, polyurethane foam case can take out in the lump with recovery gear, take back lab analysis,
Beneficial to the stability for ensureing collection sample.
The present invention compared with prior art, has the following advantages that：
1st, synchronous in-situ purification and the polar contaminants being enriched with water are realized, and recoverable reduces cost；
Without power when the 2nd, being enriched with for a long time, you can save cost, and measure the mean concentration of enrichment period, can more reflect
