A Cyclic voltammetry (VC) and Square Wave Voltammetry methods for the determination of trace amounts of phenol at carbon paste electrode modified with Natural Phosphate (NP-CPE) is proposed. The results showed that the NP-CPE exhibited excellent electro catalytic activity to phenol. The concentration of phenol and measuring solution pH was investigated.This electrochemical sensor shows an excellent performance for detecting phenol.The sensor was successfully applied to the determination of phenol in a real sample with satisfactory results.
