Ethylammonium-Selective Membrane Electrode Using p-tert-Butylcalix[6]arene Derivatives.

Ethylammonium-selective membrane electrode using p-tert-butylcalix[6]arene derivatives.

A Polymeric Membrane Electrode Based on p-tert-butyl- thiacalix[4]arene Derivative for Thorium Determination

The aim of this study was to construct and characterize an ion selective electrode for the potentiometric determination of thorium ions. On hand study we introduced a new calixarene molecule p-tert-butyl-thiacalix[4]arene derivative as ionophore for thorium(IV) selective polymeric membrane electrode. Due to the decisive role of solvent mediators, we fabricated membranes with the plasticizers DB...

Determination of the pH difference across a cell membrane using a methylammonium-selective membrane electrode.

A method was developed for determining pH differences across cell membranes using a methylammonium-selective membrane electrode, based on monitoring of the pH gradient-induced uptake of methylammonium in situ. The methylammonium electrode was constructed using calix[6]arene-hexaacetic acid hexaethyl ester as a neutral carrier and bis(2-ethylhexyl) sebacate as a membrane solvent in a poly(vinyl ...

Manganese (M-selective PVC membrane electrode based on N-(2- picolinamido ethyl)-Picolinamide as ionophore

In this research, a PVC membrane electrode for Manganese (II) ions based on N-(2-Picolinamidoethyl)Picolinamide as neutral carrier was prepared. The electrode exhibits a Nemstian responseover Mn(II) concentration range of (1.0 x10-5 t01.0 X 10-1M) with a slope of 29.3±0.5 mV perdecade of concentration with a working pH range of 4.0-9.0. It has a fast response time (

Cu(II) Ion- Selective Membrane Electrode Based on bis(N-salicylidene-3,3'-diamino diphenyl) sulfone

In order to study the Cu(II) ion selective electrode, an optimized membrane was prepared by mixing of 30 mg of PVC powdered, 5 mg of considered ionophore, 60 mg of plasticizer and 5 mg of additive. The sensor showed a near Nernstian response for Cu(II) ions over a concentration range from 1.0×0-6 –1.0×0-2 M with a slope of 28.90.5 mV per concentration decade with a working pH range of 3.5-6.3. ...
