Abstract
The solar photodegradation of five dyes, C.I. reactive red 2, C.I. rea ctive blue 4, C.I. reactive black 8, C.I. basic red 13, and C.I. basic yellow 2, were studied in a sunlight/Fe(III)-hydroxy system. It was o bserved that the photodegradation of these five dyes were pseudo-first order reactions, which has a little difference with the photodegradat ion kinetics of the dyes with UV-light as the irradiation source, The comparison between the two studies is also conducted.
