A sequential method is proposed for the determination of tryptophane and histidine by
adsorptive cathodic stripping voltammetry using standard addition and H-point standard
addition method (HPSAM). The complexes of copper (II) with the amino acids were
accumulated onto the surface of a hanging mercury drop electrode for 60s. Then the
preconcentrated complexes were reduced by square wave voltammetry and the peak
currents were measured. The effect of various parameters such as pH, concentration of ...
