Turbidity Changes during Carbamazepine Oxidation by Photo-Fenton

The objective of this study is to evaluate the turbidity generated during Fenton photo-reaction applied oxidation waters containing carbamazepine as a function factors such pH, H2O2 concentration and catalyst dosage. results let establish degradation pathways main decomposition byproducts. It found that pH affects water. Working between = 2.0 2.5, under 1 NTU due fact iron, added catalyst, in form ferrous ion. Operating at values above 3.0, iron species their oxidized state (mainly ferric hydroxide suspension) would cause turbidity. contribution these process, verifying increases linearly according ratio 0.616 L/mg Fe. Performing with oxidant concentrations (H2O2) mM, undergoes strong increase until reaching around 98 steady state. High levels can be originated by formation coordination complexes, consisting union three molecules substituted carboxylic groups (BaQD), which act ligands towards an atom Fe3+
