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 کاملElectrocatalysis at a Thin Multi-Wall Carbon Nanotube Film Modified Glassy Carbon Electrode
A sensitive and selective amperometric procedure, based on a glassy carbon electrode (GCE) modified with a thin multi-wall carbon nanotube (MWNT) film, for the determination of ascorbic acid (AA) was developed. The modified electrode showed excellent electrocatalytic activity towards the oxidation of AA. The oxidation potential of AA shifted negatively by as much as 460 mV to –18 mV (vs. SCE) a...
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 کاملStudy and Electrochemical Determination of Tyrosine at Graphene Nanosheets Composite Film Modified Glassy Carbon Electrode
A graphene nanosheets (GNS) film coated glassy carbon electrode (GCE) was fabricated for sensitive determination of tyrosine (Tyr). The GNS-based sensor was characterized by scanning electron microscope and electrochemical impedance spectroscopy. The voltammetric techniques were employed to study electro-oxidation of Tyr. The results revealed that the modified electrode showed an electrocatalyt...
