Potentiometric Solid-Contact Ion-Selective Electrode for

The best parameters were found for GC sensors for which the ion-selective membrane contained chloroparaffin as a plasticizer (S = 59.9 mV/dec, LOD = 1.6 ´ 10-6 M). The study of potentiometric selectivity coefficients has shown that the thiocyanate-selective sensor could be applied in biomedical research for determination of SCN – concentration in human saliva. ISE-potentiometric sensor for the determination of To assess the plasticizer effect, the relatively non-polar plasticizer DOS used in sensor 3 was compared to high dielectric constant plasticizer nitrophenyl octyl ether (NPOE) in sensor 5; it was observed that the latter possessed better sensitivity (LOQ = 6.66 × 10

Structure of ion selective electrode electrodes; a)

Lead(II) ion selective electrode, ISE, based on plasticized PVC membranes with 1-furoyl 3,3 diethyl thiourea as ionophore and tributylphosphate as plasticizer have been developed. The membrane was Ion-Selective Electrode – an overview | ScienceDirect Topics M. Sohail, R. De Marco, in Reference Module in Chemistry, Molecular Sciences and Chemical Engineering, 2013Introduction An ion-selective electrode (ISE) is an example of an electrochemical sensor utilizing the principle of potentiometry, or measurement of the cell potential (i.e., ISE against a standard reference electrode) at near-zero current.

Polysulfone as an alternative material to PVC in the design

Polysulfone (PS), a non-conductive polymer, is employed as an alternative material to polyvinyl chloride (PVC), the most used polymer in the design of ion-selective electrode (ISE) membranes to date. A nitrate-ISE is chosen as a model electrode to study the efficiency of PS as a polymer matrix of the membrane. Enhancing the blood compatibility of ion-selective electrode 20/8/2005 · Tecoflex without plasticizer or with low plasticizer (2:1 polymer-to-plasticizer ratio) was found to be the most biocompatible membrane material. Recently, our group demonstrated the fabrication of a blood-compatible ISE by using a silicone-modified segmented polyurethane, BioSpan-S [ 84 ].

2/3/2021 · The types of ion sensor materials that are now readily available at Alfa Chemistry include: additives, buffers, ion standard solutions, ionophores potentiometric, plasticizer, polymers, silanizing agents, solvents for ISE preparations, electrochemical substratesetc. A New Sensing Material for the Potentiometric Determination The isolated ion-exchange complex was used as a sensing material for the preparation of the PVC-based membranes plasticized with o-NPOE. For the membrane preparation, the newly synthesized sensor material (0.0018 g) was dissolved in 2 mL ofo

nitrate-selective membranes for all-solid state ISE

ISFETs showed a sensitivity between 65-69 mV/decade, depending on the plasticizer, and a linear range of 2.4 × 10-5-0.06 M. The long-term stability of ISFET sensors with trioctyl phosphate plasticizer was up to 10 months, being superior to that described in the literature for PVC membranes and even for other kind of polymers. Ethanol Sensor Using Two Chloride Ion-Selective Polymeric An ethanol sensor using two chloride ion-selective polymeric membrane electrodes (Cl-ISEs) was developed. Two different polymeric membranes were used, one with o-nitro-phenyloctyl ether (NPOE) and the other with n-decylalcohol (DA) as the plasticizer. The

11/12/2015 · The PVC membrane of an ion-selective electrode (ISE) sensitive to dibasic phosphate ions (HPO4-ISE) has not been optimized for maximum selectivity, sensitivity, and useable ISE lifetime and further work was necessary to improve its performance. Two areas of investigation are reported here: include the parameters for the lipophilicity of the plasticizer compound used and the amount of cyclic Lithium Ion Sensors24/10/2017 · 3.2. Conductive Polymer Sensors A study by Lindino in 2011 demonstrated that poly(o-methoxyaniline) (1) can be used to measure Li + ions in solution over a concentration range from 1.0 × 10 −5 to 1.0 × 10 −4 mol dm −3 [].The data show that the addition of Li + to the assembly influenced the electrochemical effects of poly(o-methoxyaniline) thus providing a detection capability.
