The suppressor has simple structure, long service life and good production performance.
Description
Technical field:
The present invention relates to a kind of chromatography of ions self-regenerated efficient ion interchange unit, relate in particular to a kind of ion chromatography self-reproduction suppresser.
Background technology:
At present, the ion chromatographic eliminator of domestic common production is all filled the superfine little ion exchange resin of granularity in cathode chamber and anode chamber.Surely belong to electromigration formula electrochemistry TVS by the TVS classification.This TVS is installed difficulty, inefficacy easily, the life-span is short, production performance is poor.
Summary of the invention:
The technical problem to be solved in the present invention is the shortcoming and defect that overcomes prior art, provides a kind of than the more advanced self-reproduction suppresser of electromigration electrochemistry TVS.
A kind of ion chromatography self-reproduction suppresser, it comprises inhibition chamber, anode chamber and cathode chamber, wherein suppress the chamber between two ion exchange resin membranes, the another side of two ion exchange resin membranes is respectively cathode chamber and anode chamber, has in the cathode chamber in negative electrode, the anode chamber anode is arranged; The connection electrical equipment that is wound with platinum wire on the POROUS TITANIUM PLATE is housed in described cathode chamber and the anode chamber.
Wherein two amberplexes that ion exchange resin membrane is a same type promptly are both anion-exchange membrane or are both cation-exchange membrane.
Be filled with anion or cationic ion-exchange resin fiber in the described inhibition chamber.
Described electrical equipment supplied gas and leacheate liquid communication, wherein the aperture in hole is 5-8 μ m on the POROUS TITANIUM PLATE.
Suppress the problem that the chamber produces bubble in order to solve in addition, the ion exchange resin lining form that between amberplex and connection electrical equipment, has one deck porous.Wherein the porous resin lining form is selected from conventional resin fibre.Described electrical equipment promptly is wound with the POROUS TITANIUM PLATE of platinum wire, have fluid course and electrolysis electrode double action, as fluid course, its good pressure-resistant performance, be difficult for stopping up, compare ion exchange resin, its structure is an integral body, directly is put in cathode chamber or the anode chamber to get final product, install easily, and the ion exchange resin of available technology adopting is the shot shape, during toward cathode chamber or anode chamber's filling, needs very skilled operation could eliminate systematic error.On the other hand, connection electrical equipment is as electrolysis electrode, and its resistance is little, and the electrolytic efficiency height is corrosion-resistant, compares ion exchange resin, and its required inhibition electric current is littler.The above advantage of connection electrical equipment makes the present invention install simply, be not easy characteristics such as inefficacy, the life-span is long, production performance is good with respect to prior art.
Description of drawings:
Fig. 1 is the ion chromatography self-reproduction suppresser schematic diagram
Among the figure: 1, suppress the chamber, 2, ion exchange resin membrane, 3, cathode chamber,
4, anode chamber, 5, negative electrode, 6, anode, 1. be the leacheate stream.
The specific embodiment:
If with Na
2CO
3The leacheate TVS is an example.Suppressing chamber 1, cathode chamber 3 and anode chamber 4 is strip.Suppressing chamber thickness is 2mm, and volume is not more than 2ml, and material is a polytetrafluoroethylene (PTFE), suppresses chamber 1 between two cation resin exchange films 2.Electrode is the titanium plate.Connection electrical equipment in cathode chamber 3 and the anode chamber 4 is the POROUS TITANIUM PLATE that is wound with platinum wire.POROUS TITANIUM PLATE thickness is not less than 1.5mm.
Work as Na
2CO
3Leacheate injects sample by infusion pump through sampling valve from liquid storage bottle, after the anion-exchange column of flowing through separates, flows out and contains sample anion A
-Leacheate, enter the TVS of this cation exchange device, at the storng-acid cation exchange resin [R-H that suppresses the chamber
+] will following reaction take place with leacheate and sample:
R-H+A
-+Na
+→R-Na+H
++A
-……②
From following formula 1., 2. as can be seen, leacheate is converted into the H that low electricity is led
2CO
3, and sample is converted into the form of acid with the form of salt, thus strengthening conductance signal, power supply is led detector and is carried out conductance measurement, and leacheate enters anode chamber and cathode chamber after electricity is led detection.
Meanwhile, in the anode chamber, under electric field action, water generation cell reaction:
2H
2O—4e→4H++O
2↑……③
The 3. middle H that produces of following formula
+Under electric field promotes, penetrate cation-exchange membrane, make the cationic ion-exchange resin regeneration that suppresses indoor, recover exchange capacity, its reaction is as follows:
R-Na+H+→R-H+Na
+……④
The 4. middle Na that forms of following formula
+Penetrate other cation-exchange membrane of side and enter cathode chamber, the concurrent row of giving birth to react in the cathode chamber:
2H
2O+4e→2OH
-+H
2↑……⑤
The Na that 6. following formula produces in cathode chamber
2CO
3The aqueous solution constantly with regenerated liquid flow through the connection electrical equipment drain in the waste water.
