The adsorption characteristics of the molecule on the modified electrode and the electron number accompanying the electrode reaction were calculated. Furthermore, a new square wave anodic adsorptive stripping voltammetry (SWAAdSV) method was proposed for the determination of CAR in drug samples. The linear concentration range and detec- tion limit of the method were found to be 0.07 ?M–2.61 ?M and 0.09 ?M, respectively. To test the accuracy of the developed method, recovery studies of CAR in the pharma- ceutical sample were carried out. With the developed method, results with high reliability, reproducibility, accuracy, and precision were obtained for the determination of CAR in pharmaceutical samples.en10.17350/HJSE19030000289info:eu-repo/semantics/openAccessArticle10143481177149
