Abstract:The electrochemical reduction behavior of selegiline was investigated by cyclic voltammetry using glassy carbon electrode and validated by square wave cathodic adsorptive stripping voltammetry. Selegiline gave one well-defined reduction peak in the potential range −0.4 to −0.5 V versus Ag/AgCl electrode. The reduction process is irreversible and partial diffusion controlled. Various chemical and instrumental parameters affecting the electroanalytical response for the determination of selegiline were investigated and optimized. Under optimized conditions, the adsorptive stripping peak current is found to be linear over the concentration range of 3.0×10 −7 -2.5×10−5 M with a detection limit of 3.04×10 −8 M and a lower limit of quantification of 1.01×10 −7 M.
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.
