The electrolytic cell is characterized in that in that the electrolytic cell is integrally formed by cathode and anode tubes 1, an intermediate pipe 2 and three supports 3. The cathode and anode tubes are provided with scales, so that the solution volume can be read out directly and conveniently, and the variations of the amount of ion can be obtained according to the variations of ionic concentration. The intermediate pipe 2 is connected with the middle parts of the cathode and anode tubes 1, so that the interfaces of a cathode chamber, an intermediate region and an anode chamber are prevented from being influenced by the agitation of bubbles produced by an electrolusis electrode. The device provided by the utility model has the advantages of compactness, simple use, easy operation and quick measurement, and can be used in manufacturing production and laboratories.
Description
Technical field
The utility model relates to electrochemical electrolysis matter solution field, is specifically related to the determinator of transference number of ions.
Background technology
In daily laboratory experiment or commercial production, need to measure transference number of ions usually.Principle and using method that tradition is measured transference number of ions are: the electrolyte solution that concentration known is housed in pipe, energized, suitably control voltage, allow very little electric current pass through electrolyte solution, at this moment positive and negative ion is moved to negative and positive the two poles of the earth respectively, generations that respond on electrode simultaneously cause near the solution concentration of electrode constantly to change, and the concentration of middle part solution is constant substantially.After energising a period of time, the solution of negative pole part/anode portion is carefully emitted, carry out weighing and analysis, thereby according to the variation of electrolyte content in negative pole part/anode portion solution and be connected on the total charge dosage of measuring on the quantity of electric charge meter in the circuit of passing through, just can calculate the transport number of ion.Traditional device has following shortcoming: 1) traditional device is made of two pipes of anode and cathode and intervalve, is difficult to steady placement, and fixedly adjusting gear bothers, and uses, collects inconvenient.2) in the mensuration process, the bubble that produces on two electrodes all can produce the solution around the electrode and stir, and middle communicating pipe on the top of electrode, the stirring of bubble anticathode chamber, mesozone and the three's of anode chamber interface probably exerts an influence, thereby influences the accuracy of experimental result.3) after energising a period of time, need pour out negative pole part/anode portion solution weigh.This just is designed into the problem of liquid transfer and liquid residue, and inconvenient operation is also brought error easily.Do not see a kind of placement at present yet steadily, collection is convenient, can avoid the influence of the stirring generation of bubble on the electrode, does not relate to the succinct device of liquid transfer and liquid residue problem simultaneously.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of transference number of ions to measure electrolytic cell, and this new device can reach bubble that steady placement, electrolysis produce not interference experiment, purpose easy to use.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of transference number of ions is measured electrolytic cell, by anode and cathode pipe 1, intervalve 2 and three supports 3 constitute, anode and cathode pipe 1 is two, be in both sides respectively, the middle part of two arms connects into an integral body by intervalve 2, and three supports 3 are in two anode and cathode pipes 1 and intervalve 2 bottoms respectively, support three arms.
Have scale 11 on the above-mentioned anode and cathode pipe 1, be convenient to read liquor capacity in the pipe, the variation of the amount of ionic species is obtained in the variation of the ion concentration of measuring in conjunction with other device that connects again.
The above-mentioned anode and cathode pipe 1 that is in both sides communicates with intervalve 2, and the both sides of intervalve 2 respectively have a switch respectively.
Above-mentioned intervalve is connected with the middle part of anode and cathode pipe, can avoid stirring anticathode chamber, mesozone and the three's of anode chamber of the bubble that electrolysis electrode produces interface to exert an influence.
A water delivering orifice is respectively arranged at above-mentioned two anode and cathode pipes 1 and intervalve 2 bottoms, and each water delivering orifice all has a switch.
Compared with prior art, the present invention has following beneficial effect:
The utility model provides a kind of transference number of ions to measure electrolytic cell.Place steadily, collection is convenient, and piston and solution are all not contaminated; Can avoid bubble anticathode chamber, mesozone and the three's of anode chamber of electrolysis electrode generation interface to exert an influence; Can directly read liquor capacity by scale, the variation of the amount of ionic species is obtained in the variation of the ion concentration of measuring in conjunction with other device that connects again, uses simply, operate simple and easyly, measures quick.
