Abstract: The current amount of Algerian safe water supplies is very small and is threatened by an ever-growing population of urban, industrial and agricultural wastewater, including a wide range of organic contaminants, such as pharmaceutical residues characterised by harmful effects on environment and human health. The purpose of this work is to study the efficacy of Fenton oxidation in the removal of paracetamol and diclofenac in distilled water in which various operating conditions have been varied. The obtained results show that Fenton oxidation is very efficient in removing paracetamol with a yield of 77%; however, for diclofenac is estimated at 32.6%. Paracetamol removal is preferred in a very acidic medium (pH = 2), while diclofenac is well removed in a weakly acidic medium. The ferrous iron content ranges between 5 mg/L and 10 mg/L for paracetamol, while it is equivalent to 5 mg/L for diclofenac. The Fenton process appears to be an efficient process for the treatment of pharmaceutical residues.
