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.
