Sensitive Voltammetric Determination of Acetaminophen at Poly(4-vinyl pyridine)/Graphene Composite Modified Electrode
This study demonstrates the use of a selective and sensitive voltammetric sensor for determination of acetaminophen (AC). This was performed by modifying a glassy carbon electrode with composite film of poly(4-vinylpyridine) and graphene sheet (P4VP/GR-GCE). The redox peak currents of AC increased significantly at P4VP/GR-GCE. The result was achieved by the synergistic effect of combined elect...
متن کاملCharacterization of Carbon Nanotubes-Gold Nanoparticles Composite Film Modified Electrode and Voltammetric Determination of Mefenamic Acid
Um novo eletrodo modificado com nanotubos de carbono foi fabricado, com base em nanotubos de carbono multi-paredes (MWCNTs) dispersos em colóide de nanopartículas de ouro (AuNPs). Foi observado que MWCNTs foram dispersos no colóide AuNPs homogeneamente. Fosfato ácido de dihexadecil (DHP) foi adicionado à suspensão para preparar um filme mais estável. O filme mostrou estrutura em rede e teve boa...

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...
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...
