متن کاملNovel Solid-Contact Ion-Selective Microelectrodes for Localized Potentiometric Measurements
The design and properties of novel type of solid-contact ionophore-based ion-selective microelectrodes are reported. The microelectrode is based on an insulated needle-shaped metallic wire with an exposed apex. The ion-to-electron transducer is made of poly(3-octylthiophene-2,5-diyl) and placed between an ion-selective membrane and the metallic tip. The ion-selective polyvinyl chloride-based me...
متن کاملSolid-Contact Reference Electrode for Ion-Selective Sensors
This work presents a flexible miniaturized ion-selective sensor consisting of a solidcontact reference electrode (RE) and ion-selective electrodes (ISE) fabricated on the same foil. The flexible ion sensor was based on AgCl electrodes screen printed on polyethylene terephthalate foil. The RE was formed by casting a mixture of plasticized polyvinylchloride (PVC) and KCl on the AgCl electrode. Th...
متن کاملA Novel Carbon Paste Electrode for Potentiometric Determination of Vanadyl Ion
Carbon paste electrode was modified by disodium 2,4-diamino-7-methylbenzo[g] pteridine-5,10-dioxide to fabricate a sensor for potentiometric determination of vanadyl ion (VO2+) in aqueous medium. The new ligand was synthesized in three steps with high yield. The optimal composition of the carbon paste was made of graphite powder (64.5%), ionophore (16.6%), paraffin oil (17.8%), a...
متن کاملA Solid-Contact Ion Selective Electrode for Copper(II) Using a Succinimide Derivative as Ionophore
All-solid-state sensors with polyvinyl chloride (PVC)-based membranes using off-the-shelf N-hydroxysuccinimide (NHS) and succinimide (Succ) ionophores were prepared using DOP (dioctyl phthalate) and NPOE (ortho-nitrophenyloctyl ether) as plasticizers. Good responses were obtained when NHS was used. The potentiometric response of the proposed electrode is independent of pH over the range 2-6. Th...
