Abstract: 

This paper reports on a systematic study of the degradation of anthracene and phenanthrene in sandy soil treated with an aqueous solution of KMnO4. A kinetic model was developed based on the soil/solution ratio to predict the degradation rates of anthracene and phenanthrene. The degradation profiles achieved with the best dosage were also determined. The proposed model provided a reasonable prediction of acceptable residual contaminant concentrations. The oxidation efficiency was found to be higher than the value provided by the treatment in which the reduction of KMnO4 to MnO2 is considered to be the only reduction mechanism.
