Abstract

The current study is on the electrochemical investigation of rutin (RTN) by modifying a carbon paste electrode (CPE) using Yttrium oxide nanoparticles (Y₂O₃ NPs) and polymerization of lycine. The Y₂O₃ NPs are synthesized by yttrium (III) nitrate and urea at 350°C. The surface morphology of synthesized NPs is confirmed by Field emission scanning electron microscopy (FESEM) and the composition of NPs by energy dispersive X-ray (EDX) analysis. The modified LMYOCPE (lycine-modified yttrium oxide carbon paste electrode) exhibits remarkable electrocatalytic redox activity toward the detection of RTN in the phosphate buffer solution (PB solution) of pH 5.7. Electrochemical techniques such as electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV) are widely employed for the investigation and evaluation of sensor performance. The fabricated electrode exhibits redox behavior for the large electroactive surface towards electron transfer. The study is novel because it combines NPs with an electrode system to create a highly sensitive, selective, repeatability, reproducibility, and stability towards RTN analysis.
