Abstract
The behaviour of copper complexes with glycylglycyl-l-histidine (GGH) was investigated using cyclic voltammetry and adsorptive differential pulse cathodic stripping voltammetry. The nature of the observed cathodic and anodic peaks was established and optimum conditions have been found for the determination of nanomolar levels of GGH by means of differential pulse cathodic stripping voltammetry after accumulation in the presence of excess copper at -0.20 V vs. AgAgCl reference electrode and using the stripping peak around -0.40 V which corresponds to the reduction of the copper(I)-GGH complex.
