【Abstract】 In this paper, the adsorptive-complex wave of Cu( Ⅱ )-L-adrenaline is proposed. In the supporting electrolyte of B. R. buffer solution at pH = 6. 90, the peak potential of the wave is about - 0. 246 V(us. SCE). The behaviour of current-potential curve and the machanism of electrode reaction were studied. The rate constant of the electrode reaction (ks), transfer coefficient (α), and the composition, apparent stability constant, dissociation constant of the complex were determined.更多还原
