Key words: modified carbon paste electrode, clay minerals, ion exchange
Voltammetry on the clay modified carbon paste electrodes was used to study of cation and anion exchange on the natural vermiculite in comparison with two natural montmorillonites. Metal ions Cu(II) and Hg(II) and organic dication paraquat were used as probe to ion exchange measurement.
