| Abstract: | A rapid and sensitive flow-injection spectrophotometric method was proposed for determination of procaine hydrochloride. This method is based on the diazotisation of procaine hydrochloride with sodium nitrite in acidic medium and the coupling reaction with α-naphthylamine. The optimal experimental conditions for the flow injection analysis were obtained by using the controlled and weighed centroid simplex method. The linear range of this method is 0～30 μg/mL. The method was successfully used to determine procaine hydrochloride in pharmaceuticals. |
