Abstract
The polarographic behaviors of Pb(Ⅱ), Cd(Ⅱ) and Cu(Ⅱ) in histidine solutions were studied at ionic strength $({\mu})$ of 0.1 with the use of $NaClO_4$ as a supporting electrolyte. The formation constants of the mixed-ligand complexes of Pb(Ⅱ), Cd(Ⅱ) and Cu(Ⅱ) were calculated by Schaap's method in the presence of both histidine and hydroxide ion. The results of the electrode reactions in the systems are also discussed.
과염소산나트륨으로 이온강도를 0.1로 조절한 histidine용액 중에서 Pb(II), Cd(II) 및 Cu(II)의 polarography적 거동을 조사하였다. 그리고 Pb(II), Cd(II) 및 Cu(II)들의 각각의 histidine과 수산화이온과의 혼합착물의 생성정수를 Schaap의 방법에 의하여 구하였으며, 또한 이 계에서의 전극반응도 검토하였다.
