Polarographic behavior of cadmium(¥±) and copper (¥±) complexes of 1,5-diphenylcarbohydrazide in dimethylsulfoxide have been investigated by the DC polarography. The reduction processes are estimated as follows; Cd(¥±)¡¤DPH Complex e-¡æ(E1/2 = -0.12V) Cd(¥°)¡¤DPH Complex. Cd(¥°)¡¤DPH Complex e-¡æ(E1/2 = -0.74V) Cd(Hg) + nDPH. Cu(¥±)¡¤DPH Complex e-¡æ(E1/2 = -0.44V) Cu(¥°)¡¤DPH Complex. Cu(¥°)¡¤DPH Complex e-¡æ(E1/2 = -0.84V) Cu(Hg) + nDPH. The limiting currents of all reduction wave are irreversible. The number of ligand and the dissociation constant for Cu(¥°)¡¤1.5-diphenylcarbohydrazide complex were found to be 2 and 5.12 ¡¿ 10-8, respectively. All reduction waves of complexes are irreversible. Based on the experimental results, the polarographic reductions of complexes in dimethylsulfoxide solution occurred in two one-electron steps.
