- Abstract: A kinetic model is proposed to describe humic acid (HA) degradation by TiO2- and ZnO-based catalysts taking intoaccount the effects of adsorption and catalyst deactivation. The model was written in Scilab and validated with data from 14references and 60 experiments, providing anR2value of 0.925. The induction time observed in some experiments was alsoconsidered in the model, improving predictions. The rate constant for HA degradation showed feasible values compared with thefirst-order kinetic constants found in the literature. This parameter indicated that the efficiency of TiO2-based catalysts was slightlyhigher than that of ZnO-based catalysts. For experiments using a minimum of 100 mg L−1catalyst, the average specific rates of 1.18×10−4and 3.27×10−3Lmg−1min−1were found for HA degradation and catalyst deactivation, respectively. Furthermore, theanalytical solution of the model provided an equation to determine the maximum HA degradation as a function of initialexperimental conditions.
