Sulfa제-Cu착화합물의 형성에 관하여 II Spectrophotometry 에 의한 Copper Sulfa-Drug Complex 의 화학조성결정

Studies on the Formation of Copper Complexes of Sulfa-Drug II.Study on Chemical Constisuent of Copper Sulfa-Drug Complex by Continuous Variation Method.

In the previous study, the composition ratios of the Cu-sulfa drugs complexes determined by gravimetric and solvent extraction method reported. In this paper, the continuous variations method has been used to know whether the complexes are simple complexes or chelates, and to recertify the composition ratios of the complexes at pH 7-8. It has been certified that the ratio of $Cu^{+2}$ ion to sulfa drugs in 1:2 from the result of this experiment.
