Abstract
The oxidation of organic compounds by Fe(II)/H2O2 (known as Fenton’s reagent) has been known for nearly a century. Recently, this reagent has been used in wastewater treatment technology. The scope and the range of applicability of Fenton and Fenton like [Fe(M)/H202] reagents in advanced oxidation technology is reviewed and selected examples of their application are presented. The rate of oxidation and the extent of mineralization of organic pollutants with these reagents is improved significantly by irradiation with UV-visible light. The usefulness of UV-visible/ Fe(II)/H2O2 and UV-visible/Fe(III)/H202 processes are exemplified through specific applications. Still, much higher improvement in the rate of destruction of organic pollutants is achieved by replacement of Fe(II)/Fe(III) with ferrioxalate. Examples are provided indicating the superiority of the UV-visible/ferrioxalate/H202 process compared to the UV- visible/Fe(II)/H202 and UV-visible/Fe(III)/H202 processes. Finally, the ferrioxalate/H202 reagent is shown to be suitable for solar detoxification of contaminated water. Again, selected examples indicate the role that this reagent can play in the solar detoxification process.
