Studies on Drug Analysis by Metal Chelate Ion II. Colorimetric Determination of Sulfa-Drugs with Dimethylglyoxime-Fe(II)

금속 chelate ion에 의한 의약품 정량에 관한 연구 (II) Dimethyglyoxime Fe(II)에 의한 Sulfa 제의 비색정량

For the colorimetric determination of Sulfa-drugs by means of solvent extraction, the sample solutions were added into dimethylglyoxime-Fe(II) complex solution, and extracted with pyridine-chloroform mixture (1:50) is a range of pH 7.5-8.5. The extracted solution shows stability and maximum absorption at 402m${\mu}$.
