Abstract

Modification of electrodes on a screen printed carbon electrode (SPCE) using polypyrrole (Ppy)-SiO 2 has been successfully conducted for phenol determination.Modification has been undertaken with electropolymerization-wise using cyclic voltammetry.Electrode resulted are used to determine phenol using cyclic voltammetry and differential pulse voltammetry.A cyclic voltammetry analysis using potential range of -1 to 1 V versus Ag/AgCl at scan rate of 100 mV/sec.Meanwhile, analysis using differential pulse voltammetry method applied potential range of 0 to 1 V versus Ag/AgCl, scan rate of 50 mV/sec, pulse rate of 0.2 V, and pulse width of 50 ms.The results provide the increase of pH and decrease of Epa potential peak.It may increase in the current of phenol.Modified SPCE Ppy-SiO 2 can be applied for phenol determination at a concentration of 10 3 -10 -5 mM with sensitivity of 7.93 μA/mM.
