Electro-Oxidation and Detection of Phenol on Metals Modified Carbon Paste Electrodes

Maallah R, Hafid A, Barakat A and Chtaini A

A variety of electrodes based on the modification of the carbon paste electrode by various metals such as, Ti, Natural phosphate (NP), kaolin, were prepared. Cyclic voltammetry and square wave voltammetry tests were performed to evaluate the electrochemical performance. The results confirmed that the modification of cabon paste electrode by metals was successful. The presence of metal in the electrode matrix enhanced the electrode stability and increases its performance for the phenol oxidation. The electrochemical study of the complex mediated graphite electrode revealed its fast electron transfer property.
