Kinetics of P-chlorophenol wastewater treatment by UV/H2O2 oxidation
UV/H2O2光化学氧化降解对氯苯酚废水的反应动力学

The photodegradation of p-chlorophenol in a hydrogen peroxide-aided photolysis process was investigated. The reaction was influenced by the original concentration of p-chlorophenol and H2O2 addition and carrier gas. With the aid of dioxygen, the removal of phenol and CODCr were reached about 96% and 50% respectively if the original concentration of H2O2 added was only half of stoichiometric calculation. A pseudo-first order kinetic model was adopted to represent the reaction.
