Abstract: This work report a Cyclic Voltammetry (CV) and square wave (SQW) methods for the determination of chelating phenol
by Moringa oleifera based on carbon paste electrode (CPE) modified with clay. The results showed that the CPE-clay
has excellent electrocatalytic activity with Moringa oleifera acting as a chelating agent for phenol. The oxidation peak
of phenol was observed around 1.00 V (vs.SCE). After Moringa treatment, the oxidation current density decreases and
this is due to a sharp drop in phenol concentrations, suggesting that Moringa oleifera has a high phenol chelating
capacity. This electrochemical sensor showed an excellent performance for detecting chelate phenol. The sensor has
been successfully applied for the determination of phenol in a real chelation.
