Further, the under water ion adsorption device is simple in mounting and convenient in carrying, and is particularly suitable for treating field on-site water samples.
Description
Affiliated technical field
The utility model belongs to the test and analysis technology field, relates in particular to yin, yang ion in a kind of planar water, is used for simple installation, the portable pretreating device of isotopics test.
Background technology
Various yin, yang ionic element isotopics in the test analysis water are to determine these yin, yang ion sources and change the most direct and effective means, and the scientific basis of necessity can be provided for water surrounding variation and water Pollution Study.Ammonium radical ion nitrogen isotope is formed, nitrate ion nitrogen and oxygen isotope is formed, the chromate ion chromium isotope is formed, test analysis such as boron istope composition in the boric acid, usually need to adopt the moon or Zeo-karb from water, to adsorb these ions, then carry out corresponding isotopics test.For prevent that the yin, yang ion changes in the water sample in transportation, influence element isotopics wherein, ionic adsorption processing water sample is carried out at the scene in the open air.At present, be suitable for yin, yang ion in the field condition adsorbing and extracting water, the pretreating device that is used for isotopics tests mainly by separating funnel, ion exchange column and filter flask by soft rubber ball be in series (Silva et al., 2000)
*Water sample flows in the ion exchange column under the control of separating funnel valve, and the moon or cation-adsorption are on resin, and the waste water sample flows in the filter flask.
There is following technical problem in the prior art:
(1) institute's water sampling amount is limited under a lot of study conditions, still, needs absorption different kinds of ions wherein simultaneously.Existing adsorption unit can not solve the convenient problem that a plurality of ion exchange columns connect simultaneously of handling owing to adopt soft rubber ball to connect.
(2), increased the complexity and the labor intensity of operating personnel of experiment because the each experiment of existing adsorption unit only can be handled single ionic, and different ions need repeat repeatedly to test.
(3) resin is easy to remain in the exchange column in the experimentation, easy-clear not, thus influence the subsequent experimental precision.

*Once proposed the yin, yang ion exchange column and connected, adsorbed ammonium radical ion and nitrate ion in the Atmospheric precipitation simultaneously, and be used for test analysis nitrogen isotope wherein and form.But exchange column adopts soft rubber ball to be connected with sebific duct in its device, is difficult for connecting and dismounting; It is worthy of note that more this device designs for field fixed point long-term observation, each sampling point needs a covering device, and does not have portable handiness.
Chang et al. (1999)
* *Also once proposed the yin, yang ion exchange column and connected, and be used for nitrate ion nitrogen and oxygen isotope and form test.But its device mainly forms based on the described device development of Silva et al. (2000), only connects a cationic exchange coloum (not providing in connection side's French) before anion-exchange column; Its device connects the dissolved organic carbon that cationic exchange coloum is used for removing water, and purpose is not element isotopics test in the positively charged ion, so whole device is mainly used in the absorption of single ionic (nitrate ion).
Therefore, need a kind of water intermediate ion adsorption unit that is applicable to field operation that is convenient for carrying of development.On the one hand, can conveniently handle the simple and easy connection simultaneously of a plurality of ion exchange columns, single experiment absorption different kinds of ions, the labour intensity of reduction experiment operator simultaneously, need overcome the deficiency of cull removing aspect.
