摘要：

Paracetamol solutions at pH 3.0 have been efficiently mineralized by environmentally clean electrochemical methods such as electro-Fenton and photoelectro-Fenton processes using a cell with a Pt anode and an O-2-diffusion cathode for H2O2 electrogeneration. This species reacts with added Fe2+ giving hydroxyl radical as main oxidant. Photoelectro-Fenton with Fe2+, Cu2+, and UVA tight as catalysts leads to complete mineralization due to the removal of the final carboxylic acids (oxalic and oxamic). When catalysts are used separately, both acids or part of them remain in solution, giving a partial (>65%) mineralization.
