Özet

Fenoprofen is an anti-inflammatory drug used especially after operations that require serious medical attention, such as surgery. It is reported that after the use of drugs such as fenoprofen, most of the drug active substances are excreted from the body through urea. Residues of pharmaceutical active substances reaching the treatment plants through the sewerage are almost never removed during the treatment period, and they accumulate in the water systems and endanger the aquatic ecosystem and living life. These drugs, which are considered in the micropollutant class in terms of both their size and the risks, have the potential to cause irreversible damage to the ecosystem and living things even at low concentrations. Advanced treatment processes are required for the treatment of this type of pollutants. Electrooxidation is an advanced electrochemical treatment process based on applying current to an electrochemical cell containing anode and cathode. In the study, drug fenoprofen was removed with electrooxidation process using boron doped diamond anode (BDD) and stainlesssteel cathode as electrode materials. The parameters reported to be effective on treatment efficiency were determined as applied current, initial drug concentration and background electrolyte concentration. In this study, the samples were taken at every 10 min from the electrochemical cell during the 80-min of electrolysis period, and analyzed spectrophotometrically to determine the optimum operational conditions that affect the process efficiency. After a serial of trials, a maximum removal rate was determined as 98% for fenoprofen at the applied current of 70 mA with the initial drug concentration of 75 µM, and the background electrolyte concentration (Na2SO4) of 100 mM.
