Development 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...
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 کاملSimultaneous Determination of Paracetamol and Ibuprofen in Pharmaceutical Samples by Differential Pulse Voltammetry Using a Boron-Doped Diamond Electrode
O presente trabalho apresenta uma metodologia simples, rápida e de baixo custo para determinação simultânea de paracetamol (PC) e ibuprofeno (IB) em formulações farmacêuticas por voltametria de pulso diferencial usando eletrodo de diamante dopado com boro (BDD). Os analitos apresentaram picos de oxidação definidos em 0,85 V para o PC e 1,72 V para o IB (vs. Ag/AgCl) sobre o eletrodo de trabalho...
متن کاملSimultaneous Voltammetric Detection of Carbaryl and Paraquat Pesticides on Graphene-Modified Boron-Doped Diamond Electrode
Monitoring of pesticide residues in food, beverages, and the environment requires fast, versatile, and sensitive analyzing methods. Direct electrochemical detection of pesticides could represent an efficient solution. Adequate electrode material, electrochemical technique, and optimal operation parameters define the detection method for practical application. In this study, cyclic voltammetric ...
متن کاملVoltammetric determination of vitamins in a pharmaceutical formulation.
Direct current polarography and differential pulse polarographic methods have been developed for the qualitative as well as quantitative analysis of vitamin B1, B2 and B6. Thiamin (vitamin B1) produced a well-defined wave in 0.1 M KCl at pH 5.2 with E(1/2)=-1.2 V and E(p)=-1.22 V versus saturated calomal electrode (SCE). Riboflavin (vitamin B2) gave two distinct waves in Britton Robinson buffer...
