Abstract :In this study, graphene oxide (GO) was synthesized by the Hummers method starting from graphite. Also, the sol-gel method synthesized yttrium oxide (YO) and was characterized by FTIR, XRD, SEM, and TEM techniques. The sensor performance of the modified electrode against the paracetamol analyte was investigated by cyclic voltammetry (CV) and differential pulse voltammetry (DPV). As a result of the optimized voltammetric methods calculated the linear working range was 0.25-10.0 µM and the LOD value was 19.0 nM. With the DPV method, advanced analytical parameters such as stability, reproducibility, and selectivity were studied. Moreover, the performance of the new sensor to detect paracetamol in tablet real samples was examined.
