Fe (II) Ion-Selective Membrane Electrode based onTetra-Phenyl Porphyrin in PVC Matrix
Fe2+ ion-selective membrane sensor has been fabricated from polyvinyl chloride (PVC) matrixmembrane containing neutral carrier tetra phenyl porphyrin (TPP) ionophore. The addition ofsodium tetraphenylborate (NaTPB) and the plasticizer DBP has been found to substantiallyimprove the performance of the sensor. The best performance was obtained with the sensor havinga membrane of composition of TPP...

متن کاملLanthanum(III) Ion Selective Electrode Based on a New Ionophore
A PVC membrane electrode based on 1-[({[(butylsulfunyl)carbothioyl]disulfanyl} carbothioyl)sulfanyl]butane as a suitable ion carrier for determination of lanthanum(III) ion was prepared. This electrode revealedsuch a good selectivity toward La3+ ion over a wide variety of other metal ions. Some experimental parametersuch as membrane composition, nature, and amount of plasticizer, the amount of ...
متن کاملChromium (III) ion selective electrode based on di(benzylamino)glyoxime
A new poly(vinylchloride) membrane sensor for Cr3+ ions based on di (benzylamino)glyoxime asan ionophore was prepared. The electrode has a linear dynamic range 1×10-6-1×10-1 mol l-1,with aNernstian slope of 20.3 ± 0.5 mV per decade and a detection limit of 2×10-7. It has a fast responsetime of
متن کاملDetermination of Lithium in Organic Matrix Using Coated Wire Lithium Ion Selective Electrode
Coated wire lithium ion selective electrode was fabricated using lithium ionophore-VI, 2-nitrophenyl octyl ether (NPOE) and potassium tetrakis(p-chlorophenyl)borate (KTpClPB) on platinum wire. Lithium ion selective electrode was giving Nernstian response from 10 -1 M to 10 -4 M with a detection limit of 3x10 -5 M. The calibration slope of this lithium ion selective electrode was found to be 58....
