Cyclic voltammetric determination of adrenaline in the presence of copper(II) ions.
Low concentrations of adrenaline (10(-5)-10(-4)M) have been found to give rise to quite marked current peaks in the cyclic voltammograms recorded for ammoniacal solutions containing a copper(II) salt at around 10(-4)M. Fast sweep-rates (20 V/sec) are generated by a cathode-ray polarograph and applied to a DME. Peak heights are proportional to the adrenaline concentration, the procedure is rapid and simple, and the reproducibility is good.
