Degradation of water pollutants such as chlorophenols(CPs)is important due to their high toxicity.The high stability of these compounds makes their degradation difficult.The oxidation of CPs at solid electrodes is not simple since several reaction pathways are possible,leading to different reaction products [1].The reaction produces phenoxy radicals,which can be coupled,forming a passivating film on the electrode.Thus,the development of electrodes that inhibit the CPs polymerization is of vital importance for achieving the CPs mineralization.In this sense,the use of chemically modified electrodes with metal-phthalocyanines(M-Pcs)gives an interesting possibility for reaching these objectives.
