In this research work, a carbon ionic liquid paste electrode (CILPE) based on butyl-3-metylimidazolium bis (trifluorometylsulfonyl) imide ( [bmim] NTF2) was fabricated and further modified with graphene/ multiwall carbon nanotubes (GR/ MWCNTs) hybrid composite .The modified electrode (GR/ MWCNTs /CILPE ) was used for measurement of carbamazepine (CBZ) in the presence of paracetamol (PA) with an excellent electrochemical catalytic behavior. The application of the electrode was investigated by cyclic voltammetry and differential pulse voltammetry. The oxidation peak currents of CBZ and PA were linear at the ranges of 1-60 µM and 2-80 µM, respectively. Also, the detection limits for CBZ and PA were 0.233 µM and 0.262 µM, respectively. The proposed sensor was successfully applied for the determination of CBZ and PA in tablet and urine samples.
