“…The concentration of hydroxyl radicals present in the system greatly influences the elimination rate of phenolics [24,25]. The concentration increases with the hydrogen peroxide concentration to a maximum value, after which it remains constant [10].…”

The characterization of radical oxidation in the degradation of phenolic compounds with H 2 O 2 /UV has been studied. A kinetic model was developed to estimate the concentration of different radical species. Radical concentration defines a determined oxidative level whose changes are analyzed for different oxidizing conditions involving pH and hydrogen peroxide dosage. This study has been developed to extend a previous radical model, only for simple phenolic solutions, to phenolic mixtures consisting of phenol and different cresols. In a mixture, the effects of composition and total amount of phenolics have a great influence on the degradation of each compound markedly modifying the behavior found in a simple solution. The application of a new extended radicalary model requires the characterization of the phenolic mixture solution through two fundamental parameters. The first one is the equivalent phenol in the mixture or phenol concentration, which gives the same oxidative level as that of the mixture case. Besides, additional information must be considered to characterize the deviation of the radical level between each compound and the mixture through the corresponding coefficient of radicalary activity. The model has been applied and verified to estimate the degradation of the different phenolics of a mixture, whatever the composition of phenolics, with good fitting to the experimental data.

“…Nearly all such research is performed in aqueous media for relevance to treating contaminated ecosystems. Examples include destruction of chlorinated compounds (Francony and Petrier 1996;Drijvers et al 1996), phenolic compounds (Petrier et al 1994;Serpone et al 1982), hydroxyanisoles and resorcinol (Takizawa et al 1996), sodium hypochlorite (Mason et al 1996), iodide and bromide (Gutierrez, Henglein, and Ibanez 1991), arylalkanes (Soudagar and Samant 1995), and glyceraldehyde (Fuchs and Heusinger 1995). These species are affected by either the sonolytically produced radical species or high temperatures.…”

The ultrasonic degradation of methylene blue at a frequency of 490 kHz was carried out in the absence and presence of TiO2 or Al2O3 particle, and the effects of amounts of particle on the enhancement of degradation rate constant estimated by assuming first-order-kinetics were investigated. The degradation reaction was enhanced by particle addition, and the apparent degradation rate constant is proportional to the increase in amount of particle. In addition, the constant of proportionality is not influenced by degraded material and ultrasonic frequency. However, particle type influences the constant of proportionality, and the value of TiO2 particle is about 6 times as large as that of Al2O3 particle.
