The oxidation rate of chlorpyrifos was examined in the pH range of 6-11 in the presenceof free chlorine. As pH decreased, the observed rate of chlorpyrifos oxidation increased.Hypochlorous acid appears to be the primary oxidant responsible for chlorpyrifos oxidation. Thereaction order with respect to both free chlorine and chlorpyrifos was found to be first order. Asimple model was developed to predict the apparent second order rate coefficient over the pHrange examined. The objectives of this study were to develop experimental approaches and amodeling philosophy to study degradation of organophosphate pesticides as a class underdrinking water treatment conditions. Includes 26 references, figures.
