Competitive adsorption and photodegradation of salicylate and oxalate on goethite
Original language description
This work deals with the competitive adsorption and photodegradation of salicylate and oxalate on alpha-FeOOH (goethite) which is a predominant crystalline modification of iron oxide present in sea sediment. pH is a crucial parameter in goethite photodissolution; therefore, by means of a pH stat titration, pH was kept constant during all experiments. For either acidic (pH 3) or neutral (pH 6) pH values oxalate is preferentially adsorbed on the goethite surface. Thus, in the presence of oxalate, adsorption of salicylate is suppressed and for oxalate concentration 2 mM is even negligible. Without oxalate the photodegradation of salicylate on goethite is negligible due to the short circuiting effect of photo-generated h(+) and e(-). When oxalate is present in the system photodissolution of goethite takes place, which results in the formation of OH radicals and photodegradation of salicylate. At pH 3 photodissolution of goethite is faster than at pH 6; oxalate disappears and salicylate pho
