Abstract

T his paper describes non-enzymatic phenol determination using poly(3methylthiophene) coated Pt electrode. Modified electrode was prepared on Pt disc surface in dichloromethane medium containing 500 mM 3-methylthiophene (3MT) and 100 mM tetrabuthylammonium perchlorate (TBAP). This electrode was used for amperometric determination of phenol in NaHSO4 / Na2SO4 (SBS) solution at pH 2.0. For this purpose, 0.70, 0.80 and 0.90 V potentials were applied and results were compared. Limit of detection and linear range were found as 4.22x10-5 and 1.41x104 - 4.00 mM (with R2=0.9932) at 0.90 V working potential, respectively. Repeatability of method was tested by using at least three modified electrode for 0.5, 1.0 and 2.0 mM phenol concentrations and relative standard deviation (RSD were found as 2.49%, 1.92% and 2.75%, respectively. To test the accuracy of method and matrix effect, phenol determination was carried out for 1.0 and 2.0 mM phenol concentrations in artificially contaminated river water samples at optimum condition and recovery values were found as 96.44% and 99.60%, respectively. Proposed method was found as simple, rapid and economic for phenol determination.
