In this study, method of determining p-nitrophenol was developed by using oxidation peak from p-nitrophenol reduction product. This determination used carbon paste electrode. The electrode consist of graphite and paraffin with composition 7:3 by weight. This method used phosphat buffer solution with pH of 7.4. The method required 60 second reduction of p-nitrophenol at potential of -1000 mV to Ag/AgCl (naCl 3 M). The calibration plots of p-nitrophenol standards were linear in the range at 0,1-10 mM of p-nitrophenol with detection limit of 0,07 mM. Percent recovery of p-nitrophenol analysis was between 91.9percent-130.5percent. |
