Advanced oxidation of antibiotics polluted water using titanium dioxide in solar photocatalysis reactor

Abstract EN

The aim of this study was to investigate antibiotic amoxicillin removal from syn¬thetic pharmaceutical wastewater.

Titanium dioxide (TiO2) was used in photocatalysis treatment method under natural solar irradiation in a tubular reactor.

The photocatalytic removal efficiency was evaluated by the reduction in amoxicillin concentration.

The effects of antibiotics concentration, TiO2 dose, irradiation time and the effect of pH were studied.

The optimum conditions were found to be irradiation time 5 hr, catalyst dosage 0.6 g/L, flow rate 1 L/min and pH 5.

The photocatalytic treatment was able to destruct the amoxicillin in 5 hr and induced an amoxicillin reduction of about 10% with 141.8 kJ/L accumulated solar energy per liter of solution.
