Abstract

Optimum conditions were found for the determination of 4-nitrobiphenyl by fast scan differential pulse voltammetry at a hanging mercury drop electrode in the concentration range 1 . 10<sup>-5</sup> to 2 . 10<sup>-7</sup> mol l<sup>-1</sup>. A further increase in sensitivity was attained by adsorptive accumulation of this substance on the surface of the working electrode, permitting determination in the concentration range (2 – 10) . 10<sup>-8</sup> mol l<sup>-1</sup> with one minute accumulation of the substance in unstirred solution or (2 – 10) . 10<sup>-9</sup> mol l<sup>-1</sup> with three-minute accumulation in stirred solution. Linear scan voltammetry can be used to determine 4-nitrobiphenyl in the concentration range (2 – 10) . 10<sup>-9</sup> mol l<sup>-1</sup> with five-minute accumulation in stirred solution, with the advantage of a smoother baseline and smaller interference from substances that yield only tensametric peaks.
