Description

technical field [0001] The invention relates to the technical field of solution oxygen removal for potential step method, in particular to a solution oxygen removal device for potential step method and an oxygen removal method thereof. Background technique [0002] Potential step method is to establish a new theoretical model of long optical path spectroelectrochemical technique-single potential step chronofluorescence method for determining the kinetic parameters of heterogeneous electron transfer. The standard rate constant and electron transfer coefficient of the electro-oxidation process verify the rationality of the theoretical model. Before the experimental solution is reused, in order to ensure the accuracy of the experimental data, it is generally necessary to deoxidize it. [0003] Most of the existing potential step method uses a solution to remove oxygen by adding an oxygen scavenger to react and remove oxygen, resulting in a serious waste of resources. Therefore,...
