Summary:An optimized voltammetric method is reported for the quantification of ibuprofen in aqueous solution using a carbon paste-multiwalled carbon nanotube composite as the working electrode. The electrode preparation and the experimental conditions were optimized; a sensitivity of 228.08 mA mol −1 L was obtained. The limits of detection and quantification were 9.1 µM and 25.5 µM, respectively, and the linear dynamic range extended from 2.36-242 µM. The repeatability was 5.35% expressed as the relative standard deviation. Using statistical analysis for the lower concentrations, the detection limit was reduced to 4.13 µM. The method was employed for the analysis of ibuprofen tablets.
