Fenton-type reactions have been developed for destruction of organic contaminants in water. This advanced oxidation process (AOP) shows promise for onsite destruction of hazardous organic compounds in water without generating secondary pollutants commonly associated with conventional treatment processes. Fenton-type reactions generate hydroxyl radical by iron(II) decomposition of hydrogen peroxide. Hydroxyl radical reacts rapidly and non-selectively with most organic compounds, so deep, even complete degradation may be achieved. The overall oxidation of organic compounds by Fenton-type reactions is, however, complex and may involve a series of steps. Understanding the oxidation mechanism, therefore, is prerequisite to proper engineering of Fenton based remediation technologies. We present here the results of a kinetic investigation on iron catalyzed oxidation of phenol by hydrogen peroxide in water in the dark.
