Voltammetric Determination of 3-Nitrobiphenyl on Meniscus Modified Silver Solid Amalgam Electrode

Abstract

Voltammetric determination of 3-nitrobiphenyl was studied using DC voltammetry (DCV) and differential pulse voltammetry (DPV) at a meniscus modified silver solid amalgam electrode (m-AgSAE). Optimal conditions were found for its determination by DCV and DPV on m-AgSAE in mixture Britton-Robinson (BR) buffer pH 6 an methanol (MeOH) in ratio 4:1 within the concentration range 1.10-4 - 4.10-7 mol L-1.
