“…This approach was extended for crown ether-facilitated alkali metal cation determination and to the detection of Ag + in the presence of a suitable ligand and has been discussed in more detail in the review by Samec et al (25) Flow-injection cells (basically equivalent to the channel flow cell) have been used by several authors, as reviewed by Samec et al (25) However, most of the studies concentrate on the analytical applications, but more detailed investigations of channel flow cells have also been published, (56,64) and digital simulations have been performed to model the responses of the cells. (65) Flow cells have shown potential in many practical applications in the fields of electroanalysis (25) and liquid-liquid extraction of metals and drugs. (66 -69) The recent advances in electrochemically modulated extraction have been reviewed by Arrigan et al (70) and…”

Simple Ion Transfer at Liquid|Liquid Interfaces

“…Jones and Dryfe [496] simulated voltammetry in liquid| liquid interface with implicit finite-difference approach, where both phases flow at different rates, showing how the shape of the current-potential profiles at forward sweep was affected.…”

“…These interfaces can be used for understanding and developing practical electroanalytical processes and devices [9,32,36,563,564]. The electrochemical methods applied to liquid|liquid interfaces have proved a useful tool for the determination of ionic analytes not easily oxidized or reduced [36,45,119,121,136,141,149,153,254,273,336,496,562,[564][565][566][567][568][569][570][571][572][573][574][575][576][577][578][579][580].…”

Ion transfer across liquid|liquid interface under forced hydrodynamic conditions. I: Digital simulations

“…Organic gels have been used to stabilize the ITIES in flow [8] and to channel configuration experiments [9,10]. Numerical simulations of ion transfer across ITIES under hydrodynamic conditions in the channel configuration experiments were developed by Jones and Dryfe [11]. An alternative approach to the study of liquid|li-quid extraction processes involves the rotating diffusion cell (RDC), introduced by Albery and co-workers [12][13][14] and modified by Manzanares et al [15] and Kralj and Dryfe [16] to study the simple and facilitated ion transfer reactions by external polarization.…”
