Removal of pharmaceuticals from wastewaters by electrooxidation

The removal of the non-steroidal anti-inflammatory drug diclofenac (DCF) was carried out by electrooxidation on Dimensionally Stable Anodes (DSA) with the composition Ti/Ruo.3Tio.70 2. The DSA electrodes were obtained by thermal decomposition of the appropriate precursors. The electrolyses were carried by using solutions of 100 mg/L DCF in 0.1 M Na2S0 4 supporting electrolyte in acidic medium at various current densities and electrolysis times. The removal of DCF was assessed by recording UV-VIS spectra and chemical oxygen demand (COD) determination of the electrolysed solutions. The results showed the mineralization of the DCF during the electrooxidation on Ti/RuojTiojCb electrodes
