Abstract

A quantitative method for determination of ketoacids, including glyoxylic acid, pyruvic acid and ketomalonic acid, in ozonated drinking water was developed by using 2,4-dinitrophenylhydrazine (DNPH) derivatization combined with liquid chromatography-electrospray mass spectrometry analysis.
