M. Aminuddin et I. Hussain, DIAZO-8-QUINOLINOL COUPLING AND SPECTROPHOTOMETRIC DETERMINATION OF AROMATIC AMINO-COMPOUNDS, Journal of the Chemical Society of Pakistan, 18(3), 1996, pp. 201-205
Sulphamethoxazole and Sulphadiazine have been estimated in different c
oncentration ranges, based on diazo-coupling with 8-Quinolinol followe
d by Spectrophotometric determination. The method is found to obey the
Beer's Lambert law for the concentration as low at 1.3x10(-2) mg/ml.
