Abstract
A sonochemical luminescent (SCL) method is proposed which permits to measure the reactivity of substrates with active oxygen species. The method involves quenching of luminol’s sonochemical luminescence by addition of a substrate and kinetically analyzing the quenching behavior. Use of the method gave findings of the reactivity of halid ions, vinyl monomers, phenols and other organic compounds. The findings showed that iodide ion was more reactive than bromide and chloride ions, and that the monomers were more reactive than the corresponding polymers. Further substrates, substituted for electron donating groups, were found to increase their reactivity, which was significant for multi-substituted phenols. The method was applicable to most of the substrates experimented.
