## 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

Vermiculite clay mineral, a novel modifier, was exploited to prepare modified carbon paste electrodes (CPEs), showing attractive ability to efficiently preconcentrate trace copper(I1) prior to its voltammetric determination. Under open-circuit conditions, copper@) was preconcentrated onto the surfac
