In the present work the influence oftemperature was studied for the degradation ofthe model compound 2-Chlorophenol (2-CP).Goethite was used as a source of iron. Theinfluence of catalyst loading and molar ratiobetween hydrogen peroxide and contaminantwas also examined.Fenton reaction has proven to be aninteresting working area; the process is usuallyfast and can have thermal and photochemicalimprovements and solar applicability.In the last decades research has beenparticularly oriented to search for theimmobilization of iron compounds in differentsupports to work with larger particle sizes inorder to avoid the otherwise necessarydownstream post treatment to separate thedissolved iron compounds existing in thehomogeneous operation.This technology, known as HeterogeneousFenton, uses hydrogen peroxide and a solidcontainer / carrier iron and also offers thepossibility of using solar radiation as a primarysource of energy, which gives the process amajor environmental value. As said before, itcan also be thermally improved.
