The oxidation of azide has been studied on TiO2 powder suspensions in water, methanol, and mixtures of the two solvents. The esr spin trapping technique has been employed to provide evidence for the formation of azidyl radicals [Formula: see text]. The results show that an aqueous alkaline medium is necessary to obtain a high production of [Formula: see text] radicals. A mechanism is proposed whereby the oxidation of [Formula: see text] is mainly due to reaction with OH• radicals which are in turn generated upon capture of holes by OH− groups adsorbed on TiO2. Azidyl anions adsorb weakly on TiO2 and do not displace adsorbed OH− from the surface.

Spin Trapping Technique

The peroxyl radical scavenging abilities of fifty Chinese herbal medicines were determined accurately by an electron spin resonance (ESR) spin-trapping technique using 5,5-dimethyl-1-pyrroline 1-oxide (DMPO) as a spin-trapping reagent. The peroxyl radical was generated by the thermolysis reaction of 2,2’-Azobis(isobutyronitrile) (AIBN) in the presence of the spin-tap DMPO and with or without sample. As a result of these studies, a strong scavenging ability of peroxyl radical was found in Chinese medicines for diseases of anti-aging and blood circulation.
