Abstract
A vermiculite-modified carbon paste electrode is used to model the pre concentration behaviour of monovalent and divalent ionic species under open-circuit conditions. Ag+ and Cu2+ ions are used as model analytes for voltammetric studies in differential pulse mode to describe the k inetics and equilibria of the accumulation process.
