摘要：The electrochemical behavior of the copper-tyrosine complex has been studied by linear-sweep adsorption voltammetry. In 0.02 mol/L Na2HPO4 buffer solution (pH = 9.6), the complex can be adsorped on a hanging mercury drop electrode and reduced at a peak potential of about -0.42 V (vs. SCE). The secondary derivative peak height is linear proportional to the concentration of tyrosine in the range 1.0 x 10(-7)-5.0 x 10(-5) mol/L. The detection limit is 5 x 10(-8) mol/L.
