Abstract
The invention belongs to the technical field of testing and analysis, and particularly relates to a pre-treatment experimental apparatus, which is used for absorbing anions and cations in water and testing isotopic composition. The apparatus is formed by connecting a Buchner funnel, one or a plurality of ion-exchange column(s) and a filtering flask in sequence through standard ground mouths. The invention can be connected with a plurality of ion-exchange columns for simultaneous absorption of multiple kinds of anions and cations in water, thereby reducing the labor intensity of the experimental operation, and can also solve the problem that the residual resin in the exchange columns can not be easily removed. Moreover, the invention has the advantages of simple installation and convenient carrying, and is particularly suitable for field treatment of water samples.
Description
Affiliated technical field
The invention belongs to test and analysis technology field, relate in particular to yin, yang ion in a kind of planar water, for simple installation, the portable pretreating device of isotopics test.
Background technology
The element isotopics of various yin, yang ions in test analysis water, are to determine these yin, yang ion sources and change the most direct and effective means, can provide necessary scientific basis for water environment variation and water Pollution Study.Ammonium radical ion nitrogen isotopic composition, nitrate ion nitrogen and oxygen isotope form, chromate ion chromium isotope forms, the test analysis such as isotopic composition of boron in boric acid, conventionally need to adopt the moon or Zeo-karb from water, to adsorb these ions, then carry out corresponding isotopics test.For preventing that in water sample, yin, yang ion changes in transportation, impact element isotopics wherein, need scene in the wild to carry out ionic adsorption processing water sample.At present, be suitable for yin, yang ion in field condition adsorbing and extracting water, for the pretreating device of isotopics tests mainly by separating funnel, ion exchange column and bottle,suction by rubber stopper be in series (Silva et al., 2000)
*.Water sample, under the control of separating funnel valve, flows in ion exchange column, and the moon or Cation adsorption are on resin, and waste water sample flows in bottle,suction.
In prior art, there is following technical matters:
(1) under a lot of study conditions, institute's water sampling amount is limited, still, need to adsorb different kinds of ions wherein simultaneously.Existing adsorbent equipment, owing to adopting rubber stopper to connect, can not solve the convenient problem that a plurality of ion exchange columns connect simultaneously of processing.
(2) because the each experiment of existing adsorbent equipment only can be processed single ionic, different ions need to repeatedly be tested, and has increased the complexity of experiment and operating personnel's labour intensity.
(3) in experimentation, resin is easy to remain in exchange column, easy-clear not, thus affect subsequent experimental precision.
Garten (1992)
*once propose yin, yang ion exchange column and connected, adsorbed ammonium radical ion and nitrate ion in atmospheric precipitation, for test analysis nitrogen isotopic composition wherein simultaneously.But exchange column adopts rubber stopper to be connected with sebific duct in its device, be difficult for connecting and dismounting; More it is worthy of note, this device designs for the long-term observation of field fixed point, and each sampling point needs a covering device, and does not have portable dirigibility.
Chang et al. (1999)
* *also once propose yin, yang ion exchange column and connected, for nitrate ion nitrogen and oxygen isotope, formed test.But its device mainly forms based on the described device development of Silva et al. (2000), only connects a cation exchange column (not providing in connection side's French) before anion-exchange column; Its device connects cation exchange column for removing the dissolved organic carbon of water, and object is not element isotopics test in kation, so whole device is mainly used in the absorption of single ionic (nitrate ion).
Therefore, need to develop a kind of water intermediate ion adsorbent equipment that is applicable to field operation being convenient for carrying.On the one hand, can conveniently process a plurality of ion exchange columns simple connection simultaneously, single experiment absorption different kinds of ions, the labour intensity of reduction experiment operator, meanwhile, need to overcome the deficiency of cull removing aspect.
