## Abstract A sensitive and selective procedure for the determination of trace tin at a carbon paste electrode was described. Each measurement cycle consisted of three steps: accumulation, reduction and stripping. The tin complex with bromopyrogallol red (BPR) was accumulated on the electrode surfa

## Abstract A method for the voltammetric determination of vanadium using a carbon paste electrode (CPE) was described. The new procedure is based on the adsorptive accumulation of the V(V)โalizarin red S(ARS) complex onto the surface of the CPE, followed by the electrochemical reduction of adsorbe
The application of potentiometric stripping analysis (PSA) to the trace determination of thallium(III) at a poly(4-vinylpyridine)amercury ยฎlm electrode (PVPaMFE) is demonstrated. Thallium(III) is preconcentrated as the anionic form, [TlCl 4 ] ร , by the ion-exchange effect into the PVPaMFE. The high
