A new method for benzocaine determination employing FIA and HPLC with electrochemical detection on a carbon paste electrode was developed. The optimum conditions for the determination were found. Carrier solution for FIA consisted of B-R buffer pH 4 (80 % methanol, v/v) and used flow rate was 1.0 mL min
À1. Mobile phase for HPLC consisted of B-R buffer pH 4 (75 % methanol, v/v) with flow rate 0.4 mL min À1 . Working potential of + 1.2 V was employed. Practical applicability of the methods was tested on the determination of benzocaine in selected pharmaceuticals. The results were in agreement with results obtained using spectrophotometric detection and with one exception also with the content declared by the manufacturer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
