Abstract :
The present research involves effectual parameters on Cefixime trihydrate removal from aqueous solutions. Antibiotics are the main contributions in pharmaceutical waste; their presence causes major concern. The extensive utilization of antibiotics in aquaculture and prescriptions has led to the cultivation of various antibiotic-resistant bacteria and genes in wastewater. The UV-LED/S2O82- process, one of the most widely (AOPs), is an effective method for industrial wastewater treatment. Sixteen experiments were required to study the effect of parameters on UV-LED/S2O82- removal of the drug. Each experiment was repeated three times )n=48) to calculate the mean of average. Outcomes revealed that among different parameters, peroxydisulfate concentration was the most efficient one. Based on the mean of average, optimized condition for drug removal was temperature of 50◦C, current intensity of 1800 mA, drug concentration of 10 ppm, peroxydisulfate concentration of 120 mM and 30 min for time. Consequently, 91.79 percent of drug degradation was achieved via optimum conditions.
