Abstract

The invention discloses a tube-shaped spectroelectrochemical sensor, which relates to the technical field of spectroelectrochemistry. The working electrode is designed in the shape of a circular shaft; The difference in aperture is 400 microns, and the gap is 200 microns. The passage of the solution in the pool is a thin-layer tubular cavity structure, and parallel light passes through the tubular cavity; the distance between the working electrode and the counter electrode of the present invention is very small, and there is It is beneficial to realize the overall electrolysis of the solution to be tested; the volume of the electrolytic cell is small, and the large area of ​​the electrode reduces the current density, which can prevent electrode polarization and is beneficial to realize the overall electrolysis of the solution to be tested. The limiting quartz window limits the working electrode, and can also pass ultraviolet and visible light.

Description

Technical field: [0001] The invention relates to a tubular spectroelectrochemical sensor, which belongs to the technical field of spectroelectrochemistry. Background technique: [0002] The known parallel-incidence spectroelectrochemical cell adopts a square structure, has a dead space, slow solution renewal, reduces sensitivity, and is difficult to machine. Thin-layer spectroelectrochemical cells used for analytical purposes should have a sufficiently long optical path to increase sensitivity by means of increased absorbance. Invention content: [0003] In view of the above problems, the technical problem to be solved by the present invention is to provide a tubular spectroelectrochemical sensor. [0004] A kind of tubular spectroelectrochemical sensor of the present invention, it is that the working electrode is designed into the shape of a circular shaft; the counter electrode is designed into a hole shape, and the difference between the aperture of the working electro...
