The electrocatalytic activity of an N,N-diethylaniline-grafted carbon (DEA/PFC) electrode was utilized to improve the sensitivity in the cathodic detection of free chlorine. Voltammetric curves showed a well-defined cathodic peak of free chlorine on DEA/PFC, lowering the overlap with that of dissolved oxygen. Amperometric measurements were applied for the determination of free chlorine for a co...

This study was designed to examine the kinetics of neurotransmitter release using the carbon fiber amperometric technique on cells in slices of mouse adrenal glands superfused with bicarbonate phosphate buffer-based solutions. The exocytotic amperometric response evoked by electrical stimulation was significantly faster than that produced after exogenous application of ACh or K+. Splanchnic ner...

The construction and performance of an amperometric microbiosensor for the determination of choline chloride by immobilizing choline oxidase on a cellulose acetate membrane are described. The procedure of choline determination involved the electrochemical detection of enzymatically generated hydrogen peroxide. This microsensor has a linear response between 0.038-0.1 mM choline chloride. The...

A new carbon paste electrode (CPE) incorporating Ru - nanoparticles (RuNP) stabilized on graphite powder was developed for H(2)O(2) amperometric detection. Cyclic voltammetric measurements, performed in phosphate buffer solutions at different potential scan rates and different potential ranges were carried out in order to evaluate the electrochemical behavior of the CPE-RuNP modified electrodes...

The paper focuses on the analysis and detection of electroactive compounds using high-performance liquid chromatography (HPLC) combined with electrochemical detection (EC). The fabrication and utilization of electrochemically treated carbon fiber microelectrodes (CFMs) as highly sensitive amperometric detectors in HPLC are described. The applied pretreatment procedure is beneficial for analytic...

A flow injection method is reported for the determination of ascorbic acid based on amperometric detection, using a cobalt(II) phthalocyanine (CoPc) modified graphite-epoxy electrode. The amperometric respons was evaluated with regard to pH, ionic strength of the electrolyte, flow rate of the carrier solution, injected sample volume and conditioning time of the electrode. The limit of detec...

A method was developed for the simultaneous determination of urinary vanilmandelic acid and homovanillic acid, which included a two step prepurification and a reversed-phase high-performance liquid chromatography with amperometric detection. Conditions were evaluated for performing measurements with the amperometric detector free from electric interference. The method was linear between 2.5 and...
