The modified titanium electrode with lead film (PbTiE) was used for determination of trace levels of cadmium using square wave anodic stripping voltammetry (SWASV). The measurement of cadmium on the PbTiE has the best reply under the following conditions of PbTiE preparation: 10–3 mol L–1 Pb2+ in HCl (pH 1.0), deposition potential of–1.40 V vs. Ag/AgCl/KClsat and deposition time of 300 s. The PbTiE reveals highly linear behavior in the concentration range 5 × 10–8 to 10–6 mol L–1, with a limit of detection of 2 × 10–9 mol L–1. Interference of nine ionic species was evaluated. The measurements were carried out without removing dissolved oxygen from the solution.
