Adsorptive Behavior and Voltammetric Determination of Hydralazine Hydrochloride at A Glassy Carbon Electrode Modified with Multiwalled Carbon Nanotubes
An electroanalytical method has been introduced for highly sensitive determination of hydralazine hydrochloride (Hy-HCl) based on its oxidation at a glassy carbon electrode modified with multiwalled carbon nanotubes (MWCNT/GCE). Studies showed that the electrochemical oxidation of Hy-HCl was accompanied by adsorption and highly sensitive responses could be achieved by adsorptive stripping volta...
متن کاملVoltammetric and Potentiometric Behavior of 2-Pyridinethiol, 2-Mercaptoethanol and Sulfide at Iron(II) Phtalocyanine Modified Carbon-Paste Electrode
A carbon-past electrode modified with iron(II) phathalocyanine (FePc) was used as a sensitive potentiometric sensor for determination of 2-pyridinethiol (2PT). 2-mercaptoethanol (2ME) and sulfide ion in aqueous solutions. The modified electrode acts as an electrocatalyst for oxidation of these compounds, and lowers the overpotential for oxidation reactions by more than 400 mV, compared to t...

متن کاملElectrochemical behavior and voltammetric determination of theophylline at a glassy carbon electrode modified with graphene/nafion.
An ultrasensitive voltammetric sensor, a simply coated graphene-Na?on suspension on a glass carbon electrode surface, was fabricated and used to investigate the electrochemical behavior of theophylline as described in the present paper. The results indicated that this voltammetric sensor exhibited a special recognition capacity to determine theophylline as well as having high sensitivity due to...
متن کاملVoltammetric Behavior and Amperometric Determination of Ascorbic Acid at Cadmium Pentacyanonitrosylferrate Film Modified GC Electrode
The present work, describes electrochemical preparation of a novel cadmium pentacyanonitrosylferrate (CdPCNF) film as a Prussian Blue analogous on the glassy carbon (GC) electrode from a solution of 5 mM CdCl2 and 5 mM Na2[Fe(CN)5NO]. The effect of experimental conditions such as pH and composition of electrodeposition solution on the peak current of the modified electrode and its stability wer...
