a new al(iii) selective membrane based on 5-bromo(salicylidene-2-amino thiophenol) as a neutral carrier in a poly(vinyl chloride) (pvc) matrix is coated on platinum wire to determine trace amounts of al(iii) ion in various samples. the sensor exhibits a good response for al(iii) ion over a wide concentration range of 5.20 × 10-7 to 1.00 × 10-2 m  with nernstian slope of 19.64 ± 0.15 mv decade-1...

Machine learning (ML) techniques have been utilized to predict specific capacity for K-ion battery based electrode materials.

a new cesium ion selective pvc membrane based on parent calix [4] arene was developed for potentiometric determination of cesium in environmental samples. the electrode based on p-5,11,17,23tetra(tertbutyl) 25,26,27,28-tetrahydroxy calix[4]arene(thc) as ionophor ,dibutyl phthalate (dbp)as plasticizer ,sodium tetra phenyl borate(natpb)and oleic acid as lipophilic salt and additive showed the ...

a poly(vinyl chloride) membrane based on a new a-dioxime derivative as membrane carrier was prepared andinvestigated as a cr(iii) selective electrode. the electrode exhibits a good potentiometric response for cr(iii)over a wide concentration range 1.0 x 10-6 to 1.0 x 10-1 m with a slope 19.5+0.5 mv/decade and low detectionlimit of 8.9 x 10-7 m. it has a fast response time < 15 s. the best perfo...

The sensor exhibits a good response for Al(III) ion over a wide concentration range of 5.20 × 10-7 to 1.00 × 10-2 M  with Nernstian slope of 19...

The effect of adding known amounts of bromide and iodide to a plasma pool an several methodologies for measuring chloride ion has been studied. Methods evaluated were coulometric, colorimetric, and ion-specific electrode. Three different types of electrodes were evaluated in order to assess any improvements which might have been made in recent years. The older electrode methodology showed an ex...

In order to preparing strontium ion selective electrode 6-(4- nitropheny1)-2-pheny14, 4- dipropy1-3, 5-diaza-bicyclo [3, 1, 0] hex-2-ene (NPDBH) was used as an ionophore. This electrode responds to Sr (II)ion with a sensitivity of 28.2 ± 0.5 mV/decade over the range 1.0 x 10-6 to 1.0 Mat pH 3.0-10.0. Thelimit of detection was 2.4 x 10-7 M. The influences of membrane composition, the pH of the t...

A nanocomposite membrane Cu2+ ion-selective electrode has been constructed using a new compound ethyl 1,2,3,4-tetrahydro-4-(4-methoxyphenyl)-6-methyl-2-oxopyrimidine-5-carboxylat (ETMOC) as a neutral ionophore. The electrode works properly. It responds to Cu2+ ion with a sensitivity of 29.5 ± 0.2 mV/decade over the range 1.0 × 10−9 to 5.0 × 10−1M at p...
