Abstract
This examination relates to the electrochemical analysis of Rutin (RT) at anionic surfactant Sodium dodecyl sulfate chemically modified graphene paste electrode (SDSMGPE) and its electrocatalytic oxidation or reduction were analyzed using the cyclic voltammetry (CV). The fabricated electrode showed an impressive electrocatalytic movement for RT with a decent electrochemical performance, low over potential and high conductivity. It was found that under ideal conditions (pH7.0) in CV, the oxidation potential of RT decrease to291 mV at the SDSMGPE as compared to a bare graphene paste electrode (BGPE). Calibration plot showed two direct unique reaches of 2.0-10 μM and 10-60 μM with a calculated detection limit (LOD) and calculated limit of quantification (LOQ) are found to be 1.17×10-8 M and 3.91×10-8M, respectively. Simultaneous investigation was completed with paracetamol (PC), effectively shows two obvious sharp tops with improved current as compared to the BGPE. The SDSMGPE has excellent reproducibility and long term stability with fine recovery in real sample of RT. Field emission scanning electron microscopy (FESEM) examination was performed to check the surface morphology of the BGPE and SDSMGPE and EIS was utilized to explore the electrode and solution interface properties.
