Abstract

Abstract We report the simultaneous electroanalytical determination of Pb 2+ and Cd 2+ by linear sweep anodic stripping voltammetry (LSASV) using an antimony nanoparticle modified boron doped diamond (Sb‐BDD) electrode. Sb deposition was performed in situ with the analytes, from a solution of 1 mg L −1 SbCl 3 in 0.1 M HCl (pH 1). Pb 2+ inhibited the detection of Cd 2+ during simultaneous additions at the bare BDD electrode, whereas in the presence of antimony, both peaks were readily discernable and quantifiable over the linear range 50–500 μg L −1 .
