Modelling of succinic acid heterogeneous catalytic ozonation on metallic foam

Mechanism of catalytic ozonation for elimination of methyldopa with Fe3O4@SiO2@CeO2 catalyst

“…The direct reaction was important for degradation of MD. Therefore, Equation was used to model reaction rate of catalytic ozonation of MD which set ozone dosage as important factors (Audirac et al, 2015). In this equation, r is the removal rate of MD (mmol L −1 min −1 ), k is the rate constant of reaction, [O 3 ] is dissolved ozone concentration (mmol L −1 ), [MD] is initial concentration of MD (mmol L −1 ), [catalyst] is catalyst dosage (mg L −1 ), and α , β , and γ are the partial kinetic orders of dissolved ozone, MD, and catalyst, respectively.…”

Kinetic modeling of nalidixic acid degradation by clinoptilolite nanorod-catalyzed ozonation process

“…These results demonstrate that k app can be empirically correlated to the ozone inlet ow rate, catalyst concentration, pH and NAD initial concentration. The expression for estimating k app at various experimental conditions can be written as eqn (19), through substituting the obtained constant values given in Table 5 into eqn (18):…”

“…In addition, there are a few studies which focused on the kinetic modeling of the heterogeneous catalytic ozonation process for contaminant decomposition. 18,19 As an example, Valdés et al, in their research including the heterogeneous and homogeneous catalytic ozonation of benzothiazole in the presence of activated carbon, reported the contribution of the heterogeneous and homogeneous reactions in benzothiazole decomposition. 20 They used the reactions in order to just develop a kinetic model for the degradation process.…”
