Spectrophotometic Determination of some Sulphonamides in Aqueous Solution Via Azo- Dye Formation Reaction
A spectrophotometric method for the determination of trace amounts of some sulphonmides (six compounds) in aqueous solutions is described. The method in based on dizotisation and coupling with pyrogallol to form a yellow coloured, stable and water- soluble azo-dye which shows maximum absorption at 4...
