Technical field
The present invention relates to atmospheric monitoring technical field, more specifically to the passive sampling of a kind of air reactive gaseous mercury
Device and the method for sampling thereof.
Background technology
Hydrargyrum is one of heavy metal and pollutant that toxicity is the strongest, by the Chinese government and United Nations Environment Programme, generation
The mechanisms such as boundary's health organization, European Union and Environmental Protection Agency are classified as priority pollutants.Due to special physical chemistry
Matter, hydrargyrum is unique heavy metal element being mainly present in air with gas phase, and can become complete by Atmospheric Transportation diffusion
Ball contact scar thing.As the main passage of hydrargyrum transmission in environment, air plays in the biogeochemical cycle of whole world hydrargyrum
Extremely important effect.Hydrargyrum existence form in an atmosphere mainly has element morphology hydrargyrum, and (GEM, zero-valent state account for air state total mercury
More than 90%), reactive gaseous mercury (RGM, divalent state) is (such as HgCl2, HgBr2, HgO, Hg (OH)2Deng) and particle mercury (PHg, two
Valence state is main).Although the ratio that reactive gaseous mercury and particle mercury are shared by air total mercury is less, but due to reactive gaseous mercury
There is higher dry deposition and wet deposition speed, be therefore deposited to the hydrargyrum on earth's surface based on reactive gaseous mercury, thus complete at hydrargyrum
Ball biogeochemical cycle also functions to important function.To some degree, atmospheric elements hydrargyrum is with other form hydrargyrum (activity
Gaseous mercury and particle mercury) between mutually convert and be largely fixed hydrargyrum long-distance migration in natural environment and returned
Become process.Therefore, in monitoring air, the concentration of reactive gaseous mercury for the improvement of air pollution and further appreciates that hydrargyrum on a large scale
Return the feature that becomes significant.
Conventional air reactive gaseous mercury actively sample mode relies on air pump to gather a large amount of gas at short notice, and with living
Property the adsorbing medium such as charcoal reactive gaseous mercury therein is trapped after be measured.Traditional active sample mode relies on supply of electric power
As power resources, it is not suitable for the sampling monitoring of remote districts；What monitoring site covered is limited in scope, and is not suitable on a large scale
Sampling is laid；Sample collector is required higher, needs the long-term operation on duty of research worker.Passive sampling apparatus can utilize nature
Wind-force or diffusion mechanism, after placing a period of time, make the target contaminant in air be captured in the atmospheric environment of monitoring
On suitable adsorbing medium, when target contaminant collect a certain amount of after be analyzed measure.
