Abstract
A kind of tubulose sediment sample oxygen barrier save set, specialty preserves for fluviolacustrine deposit thing sample length oxygen barrier in transportation, the problem solving the most perishable conversion of sediment sample.The present invention is managed by PVC (polrvinyl chloride), pvc pipe is stifled, pvc pipe lid, rubber blanket, teflin tape form.The pvc pipe added a cover in this device can be avoided managing interior experiment sediment sample and contact oxygen with the combination of teflin tape, prevents some component in sample from occurring to convert decomposition and the loss of pore water；The specification of the pvc pipe related in the present invention can unrestricted choice, length freely intercepts, it is adaptable to several samples amount sample requirement, and repeatable utilization, it is to avoid the pollution that conventional disposable valve bag store method brings.Simple structure of the present invention, it is simple to operation, farthest saves the initial condition of deposit, it is ensured that sediment sample analyzes verity and the science of the data obtained.
Description
Technical field:
The present invention relates to a kind of fluviolacustrine deposit thing sample preservation device, may be used for the oxygen barrier after surface sediment samples gathers and preserve, prevent unstable component oxidation Decomposition in deposit.
Background technology:
Along with socioeconomic high speed development, frequent and violent mankind's activity creates huge harm to the water ecological environment health such as river, lake.Deposit is the important component part of lake, river ecosystem, is pollution " source " and " remittance " in water body.After pollutant enter water body, there is quite a few to deposit in bed mud, reacted by a series of physical absorption, biological or chemical, form the mud rich in organic and nutritive salt, and to water body generation effect, become the secondary pollution source of water body.The organic of sedimentation is constantly accumulated and the most putrid and deteriorated, often consumes a certain amount of dissolved oxygen bottom water layer, causes overlying water dissolved oxygen content to decline, thus cause a series of ecological effect.Therefore, impact and the black and odorous water problem of water body are had great importance by the oxygen consumption feature of research deposit on probing into depositional environment.
Obtain the sediment sample closest to time of day and be by the key that sediment properties is analyzed, retain the intrinsic field condition of deposit, avoid contact with the premise that oxygen is accurately research deposit oxygen consumption feature.Conventional sediment sample store method predominantly utilizes valve bag to carry out sealing preservation, but often occur valve bag abrasion to cause sample to contact the phenomenon such as oxygen and pore water loss sample exsiccation during actual shipment, impacting follow-up analysis, analyzing the data that obtain can not the physicochemical property of actual response deposit.Therefore, after sample obtains, especially need to carry out sample length when transport, need a kind of low temperature oxygen barrier store method reliably badly.
Summary of the invention:
This sample preservation utilizes car refrigerator and common opaque PVC (polrvinyl chloride) drain pipe, the low temperature oxygen barrier that can complete fluviolacustrine deposit thing sample preserves, ensure that sediment sample preserves after acquirement immediately in the way of enclosed oxygen isolation the most, thus decrease sediment sample oxidation Decomposition of material in transportation.
This device mainly comprises the following steps: (1) pvc pipe: be mainly used in the preservation of experiment sediment sample；(2) pvc pipe blocks up, and is used for connecting pvc pipe and pvc pipe lid；(3) pvc pipe lid: built-in rubber pad, for airtight pvc pipe two ends；(4) teflin tape: block up the gap between the screw thread at the mouth of pipe of one end and lid for airtight pvc pipe.
The use process of this device is: the external pipe plug in pvc pipe two ends, sticks with glue agent and fill at gap, in order to avoid sample overflows；Cover rubber blanket at lid inner ring, at pipe plug other end mouth of pipe screw thread, be wound around teflin tape, screw lid；After scene utilizes sampler to obtain sediment sample, reject the large-scale impurity such as the branch in deposit, stone as early as possible, load from one end pvc pipe, sample size should be kept filled with whole pvc pipe, clean the mud at mouth of pipe screw thread, it is wound around teflin tape by same method, tightens inner ring and cover the lid of rubber blanket.The sample of good seal is placed in car refrigerator, needs freezing or stored refrigerated according to experiment.
The feature of this device is: pvc pipe is common drain pipe, has plurality of specifications, and length can freely intercept, and easily buys, it is ensured that sediment sample keeps in Dark Place, repeatable utilization, decreases the pollution that the disposable valve bag store method of routine brings.Often there is the phenomenon that the stone etc. in poorly sealed or deposited thing scratches in conventional valve bag store method, thus causes sample contact oxygen or pore water to run off；Sturdy and durable for preserving the pvc pipe of sample, it is difficult to be scratched, pore water not easily runs off.Even if owing to ferrule is tight or other reasons contacts oxygen, first contact with oxygen and react is the part of several millimeters of the mouth of pipe, when sample analysis, this part can be struck off, take the sample of pvc pipe internal layer center.The present invention combines car refrigerator, and the low temperature oxygen barrier that substantially can realize sediment sample preserves, to ensure that sediment sample analyzes verity and the science of the data obtained.

Detailed description of the invention:
Embodiments of the invention:
1 deposit difference preserving type contrast experiment
In order to prove the practicality of the present invention, elite taking two kinds of different sample preservations and carry out contrast experiment, use identical sample mode to obtain the sediment sample of same sampling point, two kinds of sample preservations are respectively the present invention and conventional monolayer valve bag preserves.
Specific implementation process: after sediment sample gathers, seals by the present invention " tubulose sediment sample oxygen barrier preservation method " respectively and preserves sediment sample, and preserve sediment sample with the sealing of monolayer valve bag.Car refrigerator cryopreservation put into by the sample sealed simultaneously, before arriving laboratory, have passed through the holding time of about 20 hours.After laboratory taken back by sample, it is analyzed immediately.
This research selects the deposit oxygen consumption (SOD) easily converted during storage and transport as monitoring index.Owing to SOD is to characterize the index of all aerobic substance unit interval oxygen consumption in deposit, various reducing substanceses in deposit and organic substance etc. easily convert when contacting oxygen.The same sample using the analysis method of SOD to preserve two kinds of methods respectively is analyzed, often group test take 3 parallel.The result of 3 groups of parallel tests shows, the SOD meansigma methods of the sediment sample that conventional method preserves is 1.016g (O2)m-2d-1, the SOD meansigma methods of the sediment sample that the present invention preserves is 1.196g (O2)m-2d-1, the sediment sample SOD using the present invention to preserve is significantly higher than the SOD of the sediment sample that conventional method preserves.Data show, the present invention is in long sample preservation under traffic condition, it is possible to be effectively prevented sediment sample oxidized, and the sediment sample that conventional method preserves is likely to be due to contact oxygen in transportation, causes Cucumber therein to convert.
