Abstract : Based on ion chromatography technology , we have developed a new method that combinesion chromatography with a conductivity detector to separate and determine the substances of oxalic acid and glyoxalic acid, which are the main substances in the electrosynthesis of glyoxalic acid. The experimental result s demonst rate that the detection sensitivity is ahead of 10- 6 grade, the coefficient of variation of retention time, the height of peak and the area of peak outperform 1%. All the recoveries of the detected substances are ranged between 98% and 102%.
