Studies on the formation of Copper Compelxes of Sulfa-Drug.

Sulfa제-Cu 착화합물의 형성에 관하여

The purpose of this work is to investigate the molar ratio, the precipitation condition and the color of copper sulfa-drugs complexes. The colors of the complexes are observed at every precipitation condition is obtained as pH 7-9. The determination of the molar ratio of complexes is able to be carried out by way of gravimetric method and solvent extraction method. The molar ratios of sulfa-drugs and copper in identified complexes are 2:1 when utilizing both methods.
