Problems solved by technology

The deoxygenation problem is not involved in the design of the spectroelectrochemical detection cell that has been reported or the deoxygenation effect is not good, so it affects the results of this type of experiment; (4) Disassembly and assembly problems
Usually, the installation, disassembly and cleaning of the spectroelectrochemical detection cell is a time-consuming process, and the working electrode (such as grid electrode) is inserted into the thin layer many times or the electrode is taken out for cleaning after the experiment, which is easy to deform and makes installation difficult in the future. Therefore, this problem needs to be improved

Embodiment

[0015] Below in conjunction with accompanying drawing 1 and 2 and by embodiment the present invention will be further described: get two cut rectangular 1cm thick translucent plates, such as acrylic plates (1 and 2), get another 0.2mm thick of the same shape Teflon or PVC film, in which a rectangular block of appropriate size is partly dug out as a diaphragm (3), and four bolt holes are drilled on the four diagonals of the light-transmitting plate (1, 2) and the diaphragm (3) respectively (4), the diaphragm (3) is clamped in the middle of the light-transmitting plates (1 and 2), and the bolts (5) are installed and tightened to form a 0.2mm thick airtight thin layer (6). The thin layer (6) is used to place the test liquid and the light-transmitting electrode (7). Drill an internal diameter at the upper end of thin layer (6) and be 12mm, deep be the cylindrical liquid reservoir (8) of 25mm. Drilling an inner diameter at the lower end of the thin layer (6) is a discharge pipe (9...

Abstract

The invention supplies thin bed spectral electro-chemical detecting pool. It is formed by a pair of light permeated boards and diaphragm. Main body upper center is set liquid storing pool cavity. Its lower part diaphragm body is set U shape opening to form sheeting spectra electro-chemical detecting pool in which grating light permeated electrode is set. Its lead wire passes through the sealing-plug in which reference electrode, counter electrode, inert gases inlet pipe and out pipe, are set. The detecting pool bottom is set liquid outlet pipe. The invention has the advantages of easy calibrating light path, adjustable thin bed thickness, high electrolysis efficiency, good deoxidizing effect, convenient installing electrode system, simple structure, and good for spectra electro-chemistry method generalization.

Description

technical field [0001] The invention relates to the fields of electrochemical analysis and optical analysis, and more specifically relates to the design and manufacture of a spectroelectrochemical detection cell. Background technique [0002] Spectroelectrochemistry is an instrumental analysis method formed by the combination of electrochemistry and spectroscopy. It can observe the molecular optical information of reactants, intermediates and products in situ and in real time during the electrochemical reaction, and track the species changes in the electrochemical process, so as to obtain Kinetic and thermodynamic parameters of electrochemical reaction are very favorable analytical means for electrochemical research, especially for the study of electrochemical reaction mechanism. [0003] The core problem of spectroelectrochemical research is the spectroelectrochemical detection cell. The design, processing, installation and disassembly of spectroelectrochemical detection c...
