Tendazole degradation by photo-NaOCl/Fe and photo …
Tendazole degradation (TBZ D) in diferent types of water matrices was assessed by applying two Advanced Oxidation Processes, both using simulated solar light (SSL), copper slag (CS) as an iron based catalyst, and separately H 2 O 2 or NaOCl as oxidants. First, optimum conditions for TBZ D were evaluated in distilled water, TBZ D = 90% at 60 min for CS …
