Oxidation of p-hydroxybenzoic acid by UV radiation and by TiO2/UV radiation: comparison and modelling of reaction kinetic

Comparative Study on the Decolorization of Orange II by Zero-valence Tin in Citric and Hydrochloric Acids

“…According to the equation 5, the reciprocal plots of initial reaction rate and initial dye concentration are linear as shown in Figure 4(b). The reciprocals of first-order reaction rate constants were reported to be proportional to initial concentrations in L-H model (Heredia et al, 2001) and the similar result was obtained in this study as shown in Figure …”

The effect of oxygen in the photocatalytic oxidation pathways of perfluorooctanoic acid

“…Differently, in the modified L-H model the light intensity can affect both kinetic constants (k r , K S ), as reported in the literature [50,51].…”

“…Photocatalytic process could be commonly described in terms of a modified LangmuirHinshelwood (L-H) model, which has been successfully used for heterogeneous photocatalytic degradation by determining the relationship between the apparent first-order rate constant and the initial content of the organic substrate [50,51]:…”

Photocatalytic and photochemical degradation of nitrobenzene using artificial ultraviolet light

“…The rate determining step of the catalyzed reaction (photocatalytic reaction) is considered to be the reaction between OH • radicals and organic molecules on the catalyst surface. Therefore the reaction rate for second order surface decomposition of nitrobenzene may be written in terms of Langmuir-Hinshelwood kinetics as [27]:…”
