%X Free radical intermediates generated in photocatalytic oxidation of some organic compound containing nitrogen atoms such as butylamine，piperidine，pyridine and so on were detected by spin trapping technique．The ESR spectra of N-centered radical adduct and C-centered radical adduct were observed．Experiment results reveal that these radicals are participants in the initial steps of photodegradation of these compounds． A mechanism which is consistent with the observation of these radicals species is elucidated．
