Catalytic ozonation process using modified activated carbon as a cataly s t for the removal of sarafloxacin antibiotic from aqueous solutions

Sarafloxacin (SAR) is an antibiotic from the fluoroquinolone group and also one of most widely used antibiotics in veterinary medicine. Potential performance appropriate effectiveness have made SAR a special place among antibiotics. Antibiotic residues environment cause many problems, important which resistance. Therefore, it necessary to remove environment. Response surface methodology (RSM) was utilized as mathematics statistics approach optimize removal efficiency using catalytic ozonation process. The obtained regression equation for response quadratic mathematical model. coefficient determination (R2), adjusted R2, predicted R2 were at 0.9939, 0.9917, 0.9855, respectively. maximum 99.3% under optimum conditions, including concentration 30.0 mg L-1, ozone dose 1.5 min-1, catalyst (modified activated carbon) 600 pH 5.0, reaction time 30 min. According results, process suitable technique can efficiently other pharmaceutical compounds.
