Abstract: In this paper, the polarographic behaviors of Cu ( Ⅱ )-histidine adsorptive-complex wave have been studied in 0.2 mol/L NaOHmedium. The experimental results show that it is a irreversible wave. The composition, conditional stability constant(K) and dissociation constant(Kb) of the complex were determined. The mechanism of electrod process has also been discussed.

Key words: Linear sweep polarography, Adsorplive-complex wave, Cu( Ⅱ )-His complex
