The electrochemical treatment of wastewater from pharmaceutical industry is a promising technique for substances which are widely using in medicinal materials. This paper deals with the electrochemical treatment of synthetic solutions containing paracetamol and pseudoephedrine. The changing of turbidity, oxidation reduction potential and chemical oxygen demand was investigated by varying the operating conditions. The results showed that turbidity, oxidation reduction potential and chemical oxygen demand which are eliminated by coagulation process and depends principally on aluminum concentration. All of the results were obtained with the use of both cathode and anode made of aluminum (Al-Al system). With this system, optimal values of current density, initial pH and electrolysis time were 45 A/m2, 6.8 and 300 min, respectively. For these optimal parameter values, the synthetic wastewater treatment of paracetamol datas better than the synthetic wastewater of pseudoephedrine.
