Abstract
A rapid method for the determination of naphazoline in antazoline- naphazoline drops is discussed. The method depends upon precipitating antazoline by a solution of sodium carbonate. Naphazoline is determined in the filtrate using (i) the modified Vierordt method and (ii) Glenn's method of orthogonal functions to correct for the unprecipitated fraction of antazoline.Keywords
