Abstract
- In the current research, ruthenium stood a conspicuous dopant for TiO2 nanoparticles, to enhance its catalytic activity. The characterization of synthesized nanoparticles was accomplished by utilizing XRD, SEM, EDX and TEM analysis. The sensing surface morphology was studied by AFM analysis. Further, we established the electrochemical behavior and detection of flufenamic acid (FFA) by utilizing ruthenium doped TiO2 nanoparticles modified carbon paste electrode (Ru-TiO2/CPE) at pH 6.0 by employing different voltammetric techniques. Modification enhances the electro-oxidation of flufenamic acid with increased current intensity. The influence of parameters like scan rate, pH, accumulation time, amount of the modifier and concentration on the peak current of the drug were studied. The effect of FFA concentration variation was studied using square wave voltammetric (SWV) technique and got lowest detection limit compared to reported techniques. The fabricated sensor was employed for the determination of flufenamic acid in biological samples.
