Simultaneous Voltammetric Determination of Ascorbic Acid and Uric Acid Using a Modified Multiwalled Carbon Nanotube Paste Electrode
This paper describes the development, electrochemical characterization and utilization of novel modified molybdenum (VI) complex-carbon nanotube paste electrode for the electrocatalytic determination of ascorbic acid (AA). The electrochemical profile of the proposed modified electrode was analyzed by cyclic voltammetry (CV) that showed a shift of the oxidation peak potential of AA about 235 mV ...
متن کاملElectrochemical sensor for the simultaneous voltammetric determination of adenosine and adenine
Electrochemical method based on voltammetry using bare and single walled carbon nanotubes (SWNT) modified edge plane pyrolytic graphite electrode (EPPGE) is proposed for the simultaneous determination of adenosine and adenine in phosphate buffer medium of pH 7.2. The oxidation peak current of both the analytes increases significantly along with the negative shift of peak potentials using SWNT/E...
متن کاملAlumina nanoparticles modified carbon paste electrode as a new voltammetric sensor for determination of dopamine
The present study examines a new dopamine sensor based on Alumina nanoparticles modified carbon paste electrode (Al2O3NPsCPE). Moreover, the present study focuses on the electrochemical act of the Al2O3NPsCPE for the detection of dopamine by cyclic voltammetry (CV) and differential pulse voltammetry (DPV). There is also a focus on the specification of the prepared modified electrode by electroc...
متن کاملSimultaneous Voltammetric Determination of Nitazoxanide and Ofloxacin in Pharmaceutical Formulation
A simple, sensitive and highly selective electrochemical method was developed for the simultaneous determination of nitazoxanide and ofloxacin in aqueous media (Britton-Robinson buffer, pH-8.36) on a hanging mercury drop electrode (HMDE) using differential pulse polarography (DPP). Using DPP a separation of about 936 mV between the peak oxidation potentials of nitazoxanide and ofloxacin present...
متن کاملSilica Nanoparticles Modified Carbon Paste Electrode as a Voltammetric Sensor for Determination of Diclofenac
The present study describes the use of a new carbon paste electrode modified by means of Silica nanoparticles prepared by a simple and rapid procedure for the determination of sodium diclofenac (DCF). Moreover, the present study focuses on the characterization of electrochemical impedance spectroscopy (EIS) and scanning electron microscopy (SEM) of the prepared Silica NPs-CPE. In this work, The...
