Voltammetric determination of tinidazole using a glassy carbon electrode modified with single-wall carbon nanotubes.
An electrochemical method based on a single-wall carbon nanotubes (SWNTs) film-coated glassy carbon electrode (GCE) was described for the determination of tinidazole. In a 0.1 M Britton-Robinson buffer with a pH of 10.0, tinidazole yields a very sensitive and well-defined reduction peak at -0.78 V (vs. SCE) on a SWNTs-modified GCE. Compared with that on a bare GCE, the reduction peak of tinidaz...
متن کاملAdsorptive 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 کاملHighly Selective and Sensitive Voltammetric Sensor for Captopril Determination Based on Modified Multiwall Carbon Nanotubes Paste Electrode
Um novo sensor voltamétrico sensível foi desenvolvido para a determinação eletroquímica do captopril (CAP) utilizando um eletrodo de pasta de nanotubos de carbono de camadas múltiplas modificado com p-aminofenol (p-APMCNTPE). O resultado mostrou que p-APMCNTPE tem uma atividade eletrocatalítica elevada para a oxidação de captopril a pH 6,0. Voltametria cíclica (CV), cronoamperometria de duplo s...

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...
