The effect of operating param eters on t he photoc atalytic removal of a ntibiotic G entamici n at aqueo us solutio n using UV-C irrad iated TiO ۲ na noparticles

The antibiotics group is on e of the most important pharmac euticals used worldwide for huma ns and veterinary purposes. The presence of broad spectrum antibiotics in a quatic environments, alb eit at low concentrations, may pose serious threats to the ecosystem and huma n health by inducing pro liferation o f bacterial drug resistan ce [۱]. Antib iotic formulation effluents are well known for the difficulty of their elimination by traditional bio-treatment methods and their important c ontribution to environm ental pollution is due t o their fluctu ating and r ecalcitrant nature [۲]. In this paper, the antib iotic gentam icin elimination using TiO۲ (Degussa P۲۵) photocatalyst u nder UV-C light has been reported. The influe nce of operational parameters on the photocataly tic reactions, including catalytic a mount of Ti O۲, light int ensity and p H has been studied.
