Simultaneous electrochemical determination of epinephrine and uric acid at 1-butyl-4-methyl-pyridinium tetrafluroborate ionic liquid modified carbon paste electrode: A voltammetric study

► 1-butyl-4-methyl-pyridinium tetrafluroborate was used for the fabrication of BMPTB/CPE by electrochemical deposition method. ► BMPTB/CPE has been characterized using SEM and its stability was evaluated. ► BMPTB/CPE acts as good biosensor and applied to the detection of epinephrine in blood serum.
