The voltammetric behavior of 9-nitroanthracene was investigated at a mercury meniscus modified silver solid amalgam electrode (m-AgSAE; inner diameter of 0.5 millimeter) by differential pulse voltammetry (DPV) and adsorptive stripping DPV (DPAdSV). Optimum conditions were found for the determination of this analyte in Britton-Robinson buffer (pH = 10.5): pulse width of 80 milliseconds, pulse height of −50 millivolts, initial potential (Ein) = −100 millivolts, final potential (Efin) = −1200, potential of accumulation (Eacc) = −100 millivolts, scan rate of 20 millivolts per second. The limit of detection was found to be 0.7 nanomole per liter (tacc = 60 seconds) by DPAdSV at m-AgSAE. The method was successfully applied for the determination of 9-nitroanthracene in drinking and river water.
