Potentiometric carbon paste sensors for lead(II) based on dithiodibenzoic and mercaptobenzoic acids.
Dithiodibenzoic (DTB) acid and mercaptobenzoic (MB) acid were studied to characterize their abilities as modifier agents for lead(II) sensors. For both sensors, the best results were obtained with modified carbon paste electrodes with 24.1% of ligand. The pH influence on the potentiometric response was studied. The selectivity coefficients for both modified electrodes were tabulated. A potentio...
متن کاملClomipramine Determination by Potentiometric PVC Membrane and Carbon Paste Sensors
Clomipramine hydrochloride, active component of an antidepressant drug, was determined in the pharmaceutical formulation by two kinds of potentiometric sensor; a PVC membrane sensor and a carbon paste electrode modified by MWCNTs and ionic liquid. Both sensors were corporated with clomipramine-tetraphenylborate ion-pair complex and they respond based on ion exchange mechanism. The best PVC memb...
متن کاملCarbon Nanotubes-Based Potentiometric Bio-Sensors for Determination of Urea
The possibility of using disposable plastic-carbon potentiometric sensors as enzyme biosensors was examined. Urease enzyme was immobilized on poly(vinyl chloride) based Hor NH4-selective membranes using cellulose acetate. This approach has resulted in a potentiometric response on changing the pH of the solution or NH4 ion content due to an enzymatic reaction that occurs between urease and urea....
متن کاملSelective Potentiometric Sensor for Isoniazid Ultra-Trace Determination Based on Fe3O4 Nanoparticles Modified Carbon Paste Electrode (Fe3O4/CPE)
Significant effects of magnetic iron oxide (Fe3O4) nanoparticles on the potentiometric behavior of carbon paste electrode for bio determination of Isoniazid aromatic drug (INH) were studied. The electrochemical performance of modified Fe3O4/CPE was investigated. The constructed Fe3O4/CPE showed high precision, sensitivity ...
متن کاملMultiwall Carbon Nanotubes Modified Carbon Paste Electrode for Determination of Copper(II) by Potentiometric and Impedimetric Methods
A chemically modified carbon paste electrode with multiwall carbon nanotube (MWCNT) was prepared and used as a sensor for Cu2+ ion. The unique chemical and physical properties of CNT have paved the way to new and improved sensing devices. A central composite chemometrics design was applied for multivariate optimization of the effects of three significant parameters (...
