Electrochemical behavior of valsartan has been carried out in Britton–Robinson (B–R) buffer solution at pH 7.0 at the mercury film electrode (MFE) by cyclic, linear sweep, differential-pulse and square-wave voltammetry. The property of valsartan adsorption at the MFE using accumulation potential of +0.10 V was observed. The effects of experimental parameters on electrochemical process at the MFE were discussed. Differential-pulse adsorptive stripping and square-wave adsorptive stripping voltammetry for the valsartan determination were proposed, linearity was found in the range of 6.0 × 10−8 to 4.0 × 10−6 mol/L. The detection limits were 2.93 × 10−9 and 3.27 × 10−9 mol/L, respectively. The proposed methods were also applied to the commercial valsartan with good recoveries.
