Abstract

The invention discloses an electrochemical in-situ spectral electrolytic cell and an application thereof. The electrochemical in-situ spectral electrolytic cell comprises an electrolytic cell body, wherein the electrolytic cell body comprises a liquid inlet, a liquid outlet and an optical detection window, the liquid inlet and the liquid outlet are formed in two opposite side walls of the electrolytic cell body, the liquid inlet is communicated with a flow injection device or a microfluidic device, and the optical detection window is arranged in the upper part of the electrolytic cell body. The electrochemical in-situ spectral electrolytic cell has the characteristics of adaptive proper spectral wavelength range, higher optical sensitivity and smaller cell time constant, is applicable to various solvents, easy to fill and clean and integrates electrochemical process sample pretreatment and wastewater treatment, and technical defects of the conventional electrochemical in-situ spectraldetection device are overcome.

Description

technical field [0001] The invention belongs to the technical field of electrochemical detection, and in particular relates to an electrochemical in-situ spectral electrolytic cell and its application. Background technique [0002] Conventional electrochemical methods do not have the ability to characterize specific molecules, and can only provide the sum of various microscopic information of the electrode reaction, which cannot meet the requirements of in-depth microscopic research, and it is difficult to accurately identify the reactants, intermediates and products on the electrode, etc. And to explain the mechanism of electrochemical reaction can no longer meet the needs of the increasingly in-depth and expanding research objects of contemporary electrochemistry. [0003] With the continuous improvement of the performance of spectroscopic instruments and the emergence of new technologies, its application range has been continuously expanded, which has greatly accelerated ...
