Direct electrochemical reduction of p-nitrophenol(PNP)was investigated on a room temperature ionic liquid N-butylpyridinium hexafluorophosphate(BPPF₆)modified carbon paste electrode(CILE).The cathodic peak potential was positively shifted and the peak currents were increased compared to that obtained on traditional carbon paste electrode(CPE).The results indicated that the presence of ionic liquid BPPF₆ on the electrode surface showed excellent catalytic ability to the electrochemical reduction of PNP.The electrochemical behaviors of PNP on the CILE were investigated by cyclic voltammetry and the conditions such as the scan rate,the buffer pH,the substrate concentration were optimized.The electrochemical parameters were further calculated with the results of the electron transfer number(n),the charge-transfer coefficient(α) and the surface concentration(Γ_Υ)as 1.76,0.37 and 2.47×10^-9 mol/cm²,respectively,for the selected reducfive peak.The results indicated that PNP showed all irreversible adsorption-controlled electrode process on the CILE.
