Simultaneous Determination of Glyoxylic Acid and Glyoxal by Dual -Wavelength and Three -Wavelength Spectrophotometry

Xu Jialiang, Wang Chengyu, Tang Xiaodong (Petrochemical Institute of East China University of Science and Technology, shanghai 200540)  
In this paper, the simultaneous UV spectrophotometric determination of glyoxylic acid and glyoxal after being transferred into oxime has been studied. The recovery of the determination of glyoxylic acid by dual wavelength spectrophotometry is l00. 9%-102. 3% (n= 6) and that of glyoxal by three-wavelength spectrophotometry is 96. 8% - l03. 0% (n= 11 ).
