## Abstract Bismuth‐film electrodes on glassy‐carbon substrates have been successfully applied for adsorptive‐stripping voltammetric measurements of trace molybdenum in the presence of chloranilic acid (CAA). The procedure is based on the preconcentration of the molybdenum‐chloranilic acid complex
The application of potentiometric stripping analysis (PSA) to the trace determination of thallium(III) at a poly(4-vinylpyridine)amercury ®lm electrode (PVPaMFE) is demonstrated. Thallium(III) is preconcentrated as the anionic form, [TlCl 4 ] À , by the ion-exchange effect into the PVPaMFE. The high
