Design and Optimization of a New Voltammetric Method for Determination of Isoniazid by Using PEDOT Modified Gold Electrode in Pharmaceuticals
Isoniazid (INH) was studied with regard to its electrochemical treatment on a strongly alkaline solution of a poly (3,4-ethylenedioxythiophene)-modified gold electrode, using both cyclic voltammetry and controlled potential techniques. This composite electrode exhibited 4-fold higher oxidation of INH, in accordance with peak densities, than the bare gold electrode. It was used the central compo...

متن کاملSquare-Wave Voltammetric Determination of Acetylsalicylic Acid in Pharmaceutical Formulations using a Boron-Doped Diamond Electrode without the Need of Previous Alkaline Hydrolysis Step
Neste trabalho descreve-se a determinação do ácido acetilsalicílico (ASA) em formulações farmacêuticas empregando voltametria de onda quadrada (SWV) e um eletrodo de diamante dopado com boro (BDD). Neste método, ASA é determinado diretamente em solução de H 2 SO 4 0,01 mol L, sem a necessidade da hidrólise alcalina. Foi obtido um único pico de oxidação no potencial de 1,97 V vs. Ag/AgCl (KCl 3,...
متن کاملDetermination of Propylthiouracil in Pharmaceuticals by Differential Pulse Voltammetry Using a Cathodically Pretreated Boron-Doped Diamond Electrode
Um procedimento simples é descrito para a determinação de propiltiouracil (PTU) por voltametria de pulso diferencial (DPV) usando um eletrodo de diamante dopado com boro (BDD) pré-tratado catodicamente. Estudos por voltametria cíclica indicam que a oxidação do PTU é irreversível a um potencial de pico de 1,42 V (vs. Ag/AgCl (KCl 3,0 mol L-1)) em uma solução tampão de Britton-Robinson (BR) (pH 2...
متن کاملDevelopment of Conductive Boron-Doped Diamond Electrode: A microscopic, Spectroscopic, and Voltammetric Study
Building on diamond characteristics such as hardness, chemical inertness and low electron emission threshold voltage, the current microscopic, spectroscopic and voltammetric investigations are directed towards improving the properties of electrode coating materials for their future use in clinical studies of deep brain stimulation via fast-scan cyclic voltammetry (FSCV). In this study we combin...
