Monitoring Ion Activities In and Around Cells Using Ion-Selective Liquid-Membrane Microelectrodes

Selective Transport of Propylene by Silver Ion Complex Through an Immobilized Liquid Membrane

Potassium-specific ion-exchanger microelectrodes to measure K + activity in the renal distal tubule.

The recent introduction of miniature liquid ion-exchanger electrodes provides the possibility of overcoming previously encountered limitations on the measurement of specific ionic activities in biological fluids. Hydrogen ion and sodium ion activities have been stuccessfully determined by means of glass-membrane electrodes(l-5). However, in the presence of sodium, glass electrodes are usually i...

High-Sensitive and Selective Liquid Membrane Electrode for Direct Determination of Trace Amounts of Chromium

N-(2H-[1,2,4]thiadiazolo[2,3-a]pyridine-2-ylidene)benzamide was used as a selective sensing material in the PVC membrane to construction of a new chromium ion selective electrode. This liquid membrane electrode worked well with a Nernstian response of 19.7 ±0.4 mV decade-1 of Cr(III) in a wide dynamic concentration range of 8.0× 10-6-1.0×10-1 M. The electrode had relatively short response time ...

SELECTIVE TRANSPORT AND EXTRACTION OF ALKALI METAL CATIONS (Na & K ) THROUGH CHLOROFORM LIQUID MEMBRANE BY DIETHYLENE GLYCOL MONOBUTYL ETHER AND DIETHYLENE GLYCOL DIBUTYL ETHER

A liquid membrane containing diethylene glycol monobutyl ether (2) shows specificity for K ion in transport while diethylene glycol dibutyl ether (1) was selective for Na over K . As an extractant, ligand 2 exhibited pronounced extraction selectivity for K over Na in comparison with ligand 1

Supported Liquid Membrane in Metal Ion Separation: An Overview

Using liquid membrane and, in particular, supported liquid membrane (SLM) is a novel method of separation in comparison to other methods such as adsorption, extraction and ion exchange. SLM is a combination of simultaneous extraction and disposal whose high efciency and capability is proven by many studies. So far, many researchers have utilized SLM in various scientifc...
