Abstract	25℃, 용액의 이온세기 μ= 1.0(NaNO3) 및 pH 8.0인 조건하에서 카드뮴 -Oxalate-Citrate계의 단일 및 혼합 리간드 착물에 관한 연구를 미분펄스폴라로그라피적으로 수행하였다. DeFord-Hume 및 Schaap-McMasters의 도표법을 이용하여 단일 및 혼합 리간드 착물의 안정도상수 값을 구하였다. log β11, log β12 및 log β21값은 각각 4.91, 4.99와 5.18이었으며 이들 값으로부터 혼합 리간드 착물계의 여러 평형관계 등을 논의하였다. The simple and mixed ligand complexes of cadmium-oxalate-citrate systems have been studied with differential pulse polarography at 25℃, in the solution with constant ionic strength, μ= 1.0 (NaNO3) and pH 8.0. Using the graphical methods by DeFord-Hume and Schaap-McMasters, the overall stability constants for the mixed ligand complexes, βij, were found to be: log β11 = 4.91, log β12 = 4.99, and log β21 = 5.18, respectively. Various equilibria involved in the mixed system have also been discussed.
