摘要
利用醛基的成肟反应，用双波长法、三波长法同时测定乙醛酸、乙二醛的含量。它们的回收率分别为１００．９％～１０２．３％（ｎ＝６）和９６．８％～１０３．０％（ｎ＝１１）。
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 ).
