摘要：

During the electrosynthesis of glyoxylic acid through oxalic acid, the main components in the electrolyte are oxalic acid, glyoxylic acid,glyoxal, and glycollic acid. To optimize and control the manipulated parameters, it is necessary to determine the concentrations of the reactant,product and by-products. Generally, the chemical titration methods were used to determine the total acid,total aldehydes, oxalic acid, and glyoxal, respectively. The glycollic acid contents was estimated by subtraction. These analytical methods are tedious and time-consuming.
