Abstract

The invention relates to an electrolytic cell. The electrolytic cell comprises a base, a cavity and an optical window, wherein the base is used for supporting a working electrode; the cavity and the base are packaged together by a nut, thus ensuring the sealing of the electrolytic cell; and ultraviolet-visible light vertically passes through the optical window and shines on the surface of the working electrode.

Description

technical field [0001] The invention relates to an electrolytic cell. In particular, the present invention relates to an electrolytic cell for flow ultraviolet-visible spectroscopy. Background technique [0002] Ultraviolet-visible spectroscopy is a powerful material characterization technique that can provide information on the molecular structure of substances. Each absorption peak matches a certain fixed chemical bond. It is an ideal tool for studying electrochemical reactions at solid-liquid interfaces. If the ultraviolet-visible spectroscopic analysis method is combined with the research on the reaction mechanism of electrochemical electrodes, a new discipline will be formed: spectroelectrochemical method. Since the method was proposed in the 1970s, it has developed rapidly and has become an The independent branch of analysis is used to measure the species and concentration of electrochemically active particles in the solution and their changes with time and electrode ...
