Differential pulse cathodic stripping voltammetry of the copper complexes of glycyl-L-histidyl-glycine at a hanging mercury drop electrode



Differential pulse cathodic stripping voltammetry of the copper complexes of glycyl-L-histidyl-glycine at a hanging mercury drop electrode



Talanta 40(10): 1481-1488



The behaviour of the copper complexes of glycyl-L-histidyl-glycine (GHG) was investigated using cyclic voltammetry and differential pulse voltammetry after their adsorptive accumulation on the surface of a hanging mercury drop electrode (HMDE). The nature of the observed cathodic and anodic peaks was established and optimum conditions were found for the differential pulse cathodic stripping voltammetric detemination of GHG at the 1 × 108M concentration level using adsorptive accumulation at 0.20 V vs. Ag/AgCl reference electrode and the cathodic stripping peak around 0.4 V (pH 8.3). This peak corresponds to the reduction of the Cu(I)—GHG complex formed at the HMDE surface as an intermediate in the reduction of Cu(II)—GHG to Cu(O)amalgam.
