Abstract
|
|
|
|
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 is 1 : 2 from the result of this experiment.
