Abstract
The utility model relates to a field electrochemical-paramagnetic flow electrolyzer which is composed of a glass electrolyzer, a fluoroplastic intermediate converting sleeve and a quartz sample tube and is provided with a working electrode, a platinum and a silver / silver chloride reference electrodes and auxiliary electrode platinum wires. Because the three electrodes are reasonably arranged according the different requirements of electrochemical and paramagnetic measurement for the electrolyzer, the utility model is nicely suitable for the electrolytic-paramagnetic requirements of different systems, converting heads can be switched with different electrolyzers and quartz tubes as required so that the utility model is suitable for the electrolytic-paramagnetic measuring requirements of the different systems, and the utility model can be formed into series of electrolyzers so as to make experiments have accurate results.
Description
It is on-the-spot that the utility model belongs to, the design of galvanochemistry-paramagnetic flow-type electrolytic cell.
Applied chemistry 5 (1), 88-90 (1988) discloses a kind of SEESR electrolytic cell of the TE011 of placing resonator cavity, this electrolytic cell is made up of with teflon sleeve with quartz capillary aquarium and is connected, in the aquarium of upper end, lay three electrodes, this electrolytic cell is owing to be that pipe is inconsistent with two diameters of kapillary under the aquarium, and it connects only uses shape sleeve pipe ease of connection seepage solution always, and solution is in case leak the resonator cavity that will pollute in the paramagnetic instrument, bring very big infringement, make its adaptive surface little.Owing to it can not constantly replenish fresh electrolyte its application is restricted simultaneously.
The utility model purpose is that design is a kind of with glass electrolytic tank, fluoroplastic intermediate conversion cover and quartz specimen pipe and be furnished with the flow-type electrolytic cell of working electrode platinum filament, silver/silver chloride contrast electrode and auxiliary electrode platinum filament formation.
The on-the-spot electrolytic cell that flows is mainly used to detect highly unsettled electron paramagnetic resonance active substance, can not use static electrolytic cell in this case, because the electron paramagnetic resonance active substance in the work seldom, and disappearance speed is too fast, be difficult to obtain the electron paramagnetic resonance signal, and in the electrolytic cell that flows, owing to constantly replenish fresh electrolytic solution, the electron paramagnetic resonance active substance produces continuously, therefore near the free radical that can keep enough concentration the working electrode can detect electron paramagnetic resonance spectrum.The mobile electrolytic cell of the utility model design is just according to above job requirement design and reach request for utilization.
Embodiment of the present utility model is described below in conjunction with the accompanying drawings:
Accompanying drawing 1 is field electrochemical-paramagnetic flow-type electrolytic cell synoptic diagram, glass electrolytic cell (4) is a garden shape cup-shaped among the figure, its bottom center has a short tube, conversion sleeve (6) is made with fluoroplastic, on it, following two ends conversion head is the garden tubulose, upper end diameter is mated greater than the short tube diameter of glass electrolytic cell (4) bottom center, lower end diameter is greater than quartz ampoule (7) upper end diameter, match with it, quartz ampoule (7) lower end connects solution circulation pipe (9), contrast electrode (1) outer casing glass tube inserts in the electrolytic cell (4), the short tube of working electrode (2) by cup-shaped electrolytic cell (4) directly insert the quartz ampoule middle part its one section of the short tube of electrolytic cell (4) bottom center, cover fluoroplastic overcoat, auxiliary electrode (3) is the garden tube that a thin platinum filament is rolled into, its diameter matches with it less than glass electrolytic cell lower end short tube internal diameter, draw with a platinum filament that is welded on the thin platinized platinum coboundary of garden tube the upper end, conversion head fixed cover (5) is 2 garden tubular fluoroplastic covers, on, the garden tubulose conversion head external diameter of following two internal diameters and conversion sleeve (6) matches, play the effect of lock ring, auxiliary electrode (8) is put in the lower end of quartz ampoule (7), auxiliary electrode (8) is a ring-type platinum filament, one end becomes garden ring along the quartz ampoule inwall, the other end is drawn in quartz ampoule lower end and discharging tube interface, with adhesive tape its outlet is adjacent to seepage-proof liquid.
Place three electrodes like this so that contrast electrode is tried one's best near working electrode to improve the accuracy of control of Electric potentials, adopt two auxiliary electrodes and make it outside resonant cavity, in order to avoid auxiliary electrode itself is to the reflection or the influence of the reaction product on the auxiliary electrode to measuring of microwave.
During test three electrodes are connected on the potentiostat, electrolytic cell is inserted in the resonator cavity of electron paramagnetic resonance spectrometer magnet central authorities, three electrodes are meant the working electrode of determining to be studied the interface, the contrast electrode and the auxiliary electrode that electric current is provided that keep the constant reference current potential, by three electrodes, research oxidation reduction reaction is noted the free radical spectrum that electrolysis produces on electron paramagnetic resonance spectrometer.
Galvanochemistry-paramagnetic flow-type the electrolytic cell of the utility model design because galvanochemistry and the different requirements of paramagnetic measurement to electrolytic cell have reasonably been considered in three electrode settings as far as possible, and has been fit to different system electrolysis---the needs of paramagnetic better.Simultaneously conversion head can take as required up and down different-diameter respectively the electrolytic cell of different short tube diameters with the upper end match with the quartz ampoule of lower end different-diameter, make it not only can measure the non-aqueous solution system, and can survey water solution system, solved water and made paramagnetic can't transfer the difficulty of film, reached the different system electrolysis of adaptation---the needs that paramagnetic is measured by microwave absorbing.
