Recent advances in CREC

CREC researchers have addressed recently the application of Fe cations as additives to enhance the performance of PC reactions employing inexpensive procedures. This was sought owing to the characteristic properties and behavior of Fe cations in a PC reaction. Phenol and similar aromatics were selected as model pollutants given their refractory nature in water treatment and health problems associated with their presence in drinking water. 

In this respect, the effect of Fe cations on bofh the oxidation rate and complete mineralization rate of phenol and alike aromatic compounds was considered. Optimum conditions were reviewed to use Fe cations as reaction enhancers (henceforth PC reactions involving optimum Fe concentrations are called Fe-assisted PC reactions). This also involved the assessment of effect and mechanism of Fe ions on fhe PC reaction of phenol and other selected aromatic species. A systematic comparison between the kinetic reaction schemes for both unpromoted PC and Fe-assisted PC reactions for the selected model pollutants was also a primary emphasis. Last, the estimation of the enhancement through efficiency factor calculations was described.
