title: Indirect electrochemical detection of cations with cerium(III) in the mobile phase.
abstract: Cerium(III) has been used in the mobile phase for indirect electrochemical chromatography of cations. Lithium, sodium, ammonium, and potassium ions have been separated within 4 min and detected with both glassy carbon and Kel-F wax carbon paste electrodes. With a Kel-F wax/graphite electrode at 0.7 V, the detection limit for sodium, ammonium, and potassium ions are 1.5, 1.1, and 2.0 ppm, respectively.
