Description
Technical field
The utility model relates to metallic ion in a kind of collection water body and the soil, be used for to support with fixing different-thickness diffusion mutually, solid bond mutually with place liquid in conjunction with the adjustable biological available state sampling thief of the metallic ion overcoat of multi-usage thickness mutually.
Background technology
In most of ecological toxicology researchs, the biological available state content of heavy metal in soil and total metals have certain correlativity.But most of researchers recognize in the heavy metal in soil total amount to be that plant, microorganism and soil animal are unavailable greatly.The measurement that has data to be presented at free ion activity in the soil liquid provides better reference.Plant causes the heavy metal concentration in the soil liquid to descend to the absorption of heavy metal, impel soil particle attitude heavy metal to replenish to the soil liquid thus, this dynamic reaction process be can not ignore, and this dynamic reaction process has material impact for bioavailability of heavy metals.
1994, gradient diffusion film technology (Diffusive Gradients in Thin-films by Britain scientist Davison and a sky invention, DGT) can more authentic and valid simulation soil dynamic reaction process, and performance model can estimate the kinetic parameter of soil dynamic process, thereby can assess the importance of soil dynamic process better.Formed by filtering membrane, diffusion barrier and adsorption film and the plastic wrapper of fixing this trilamellar membrane based on the DGT device of DGT technological development.Wherein filtering membrane is mainly used to protect diffusion barrier and adsorption film, avoids the particle in the environment to be measured to enter the DGT device; Diffusion barrier can allow the ion of solution state freely spread; Adsorption film can be selected different absorption materials according to experiment purpose.Along with science and technology development, the DGT material is also being updated and is being upgraded, and reaches in conjunction with the combination of phase mutually etc. as liquid in conjunction with the use of phase, the different diffusions of thickness, makes traditional support can not satisfy the demand of practical application.Open the support of the DGT device of vast and boundless teacher's invention and is formed by base and enclosing cover, have simple structure, advantage such as volume is less, and is easy to carry, but can not be used for placement liquid in conjunction with phase.
The patent No. is that overcoat is made up of sampling container and base plate in the patent of (201120009011.8) " passive sampling apparatus of metallic ion in water environment or the soil pore water ", sampling container and base plate are fixed by screw, there is the hole of cylindrical shape sampling container inside, place the right cylinder of band circular cone cavity in empty, though this invention has solved liquid in conjunction with the application on DGT, this overcoat also exists and removes and installs the deficiency that complexity, volume are big, can not use solid bond to be on good terms.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provides the multi-usage thickness in a kind of DGT of utilization technology collection water body and the soil the adjustable biological available state sampling thief of metallic ion overcoat.
The utility model for achieving the above object, the technical scheme that adopts is: the biological available state sampling thief of the metallic ion overcoat that a kind of multi-usage thickness is adjustable, it is characterized in that: comprise supporter, inner core, enclosing cover, sealing rubber ring, described supporter is the plastics ring bodies, be provided with a circle boss in the interior ring bottom of supporter, outer ring surface at supporter is provided with external thread, is provided with two symmetrical rectangular recess in the upper surface of supporter; Described inner core is the plastics rounded body, and an end face of inner core is the plane, and the other end is cone-shaped groove, is provided with two rectangular preiections that match with rectangular recess at the periphery of inner core; Described enclosing cover is the plastics rounded body, is provided with internal thread at the lid inwall of enclosing cover; Two described sealing rubber rings are bonded in respectively on the periphery of inner core, and an end of described inner core is arranged in the interior ring of supporter, and outside the ring, described enclosing cover was screwed onto with supporter in the other end was emerging in.
Characteristics of the present utility model are: the metallic ion diffusion that different-thickness can be set mutually with in conjunction with mutually, and solid bond mutually and the liquid combination all can use at this support mutually.Sealing property of the present utility model is strong, uses in the time of can sampling in water body and sediment, and usable range is wide.
