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
