Sažetak
Formation of L-histidine and copper complex in 1 : 1 ratio in the pH range from pH = 4 to pH = 10 was studied. Experiments were conducted in an electrochemical cell with a working glassy carbon electrode, reference Ag/AgCl electrode and a platinum wire counter electrode. The results have shown that copper and histidine complex is formed in the range from pH = 6 to pH = 10 and that the oxidation potential of metal ion in the complex became more negative with the increase in pH. Oxidation peak current increased until pH = 8, and thereafter decreased, while oxidation peak potential linearly decreased with increase in pH value.
