摘要：
A kinetic model for the oxidation of atrazine by H2O2/UV in dilute aqueous solutions ([Atrazine](0) < 2 mu M) has been tested in a batch reactor. In this model, direct photolysis and oxidation by hydroxyl radicals are assumed to be the main reactions in the decomposition of atrazine by H2O2/UV. The data showed that the model can be used to predict the effects of some parameters (hydrogen peroxide dose, pH, bicarbonate alkalinity, ...) and to estimate values of quantum yield of photolysis, rate constants for the reaction of hydroxyl radicals with atrazine and of the scavenging term (Sigma k(i)S(i)) of natural waters.
