The method developed in this study was successfully applied to drug and urine samples. The developed voltammetric method was highly selective and gave satisfactory recovery results in urine and pharmaceutical samples. The results of the voltammetric method were compared with the spectroscopic method and it was determined that the results were compatible.

This procedure showed a linear response in a Britton-Robinson (pH 9.0) media within the concentration range of 0.2-1.8 µM and limit of detection (LOD) and the limit of quantification (LOQ) values were determined to be 0.073 μM (0.133 μg mL-1) and 0.243 μM (0.443 μg mL-1), respectively.
