Abstract
A promising electrochemical sensor for the determination of nicotine (NIC) was developed by electrodeposition of Ce-Nanoparticles on a carbon paste electrode (CPE). The interaction of nicotine was studied using cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), Scanning electron microscope (SEM) and Energy Dispersive X-Ray Analysis (EDX) techniques, in both aqueous and micellar media. The NIC Measurements were carried out in Britton–Robinson (B–R) buffer solution of pH range (2.0–8.0) containing (1.0 mM) sodium dodecylsulfate (SDS). The linear response range of the sensor was between 8 × 10−6 and 10−4 M with a detection limit of 9.43 × 10−8 M. Satisfactory results were achieved for the detection of NIC in real samples as urine and different brands of commercial cigarettes.
