摘要：

The possibility Of HO2 formation and its diffusion into the gas phase during the photocatalytic degradation of methy ethyl ketone (MEK) on TiO2 has been studied using the very sensitive and selective detection method of continuous wave cavity ring down spectroscopy (cw-CRDS), coupled to a continuous photolysis reactor. No HO2 radicals could be detected, given a detection limit of 3.2 x 10(9) cm(-3).
