A photometric method of determining sulphonamides in milk, based on the diazo reaction with the para-amino group and coupling of the diazo salt with Tsuda's reagent, was found capable of detecting residues at >0.1 mg/l. milk with satisfactory accuracy and speed. Residues were detected in milk for less than or equal to 5 milkings after intravenous injection of cows with a sulphadimidine preparation.
