[ 1 ] - Ultra-trace Determination of Palladium(II) by Spectrophotometric Flow Injection Analysis

Nowadays, palladium compounds due to their especial characteristics used in different industries, mainly in electrical power sources and chemical productions as a catalyst. Therefore, Pd concentration is increasing in our around that can be contaminant our environment due its toxic effects. In this work, a simple, selective and rapid flow injection method of analysis (FIA) has been developed fo...

[ 2 ] - Voltammetric Determination of Penicillamine Using a Carbon Paste Electrode Modified with Multiwall Carbon Nanotubes In the Presence of Methyldopa as a Mediator

A multiwall carbon nanotubes-modified carbon paste electrode (MWCNTs/MCPE) wasfabricated and used to study the electrooxidation of penicillamine (PA) by electrochemicalmethods in the presence of methyldopa (MDOP) as a homogeneous mediator. Theelectrochemical oxidation of PA on the new sensor has been carefully studied. The kineticparameters such as electron transfer coefficient, α, and catalyti...

[ 4 ] - Voltammetric determination of glutathione in pharmaceutical and biological samples using multiwall carbon nanotubes paste electrode in the presence of rutin as a mediator

A new sensitive, selective and nonexpensive electrochemical sensor was developed for electrocatalyticdetermination of glutathione (GSH)in pharmaceutical and biological samples. GSH is a tripeptide thiol present in all eukaryotic and probiotic cells. A voltammetric studyof GSH has been carried out at the surface of carbon paste electrode modified with multiwall carbon nanotubes(MWCNTPE) in the p...
