Lipophilic N-tetrabenzylcylam, III, at pH 4-7 was found to be a good carrier for liquid membrane transport of dicarboxylate anions, such as o-phthalate, and of amino acid anions52). It was suggested that the diprotonated species, H2L2+, is an active carrier species for anions. [Pg.125]

Novel dithiane-spiro-crown ethers 283 have been prepared from 5,5-di(hydroxymethyl)-1,3-dithiane. These compounds 283 were lithiated and, after reaction with isophthalic aldehyde, furnished products 284, which are capable of efficient liquid membrane transport of methyl viologen (Scheme 74)453. [Pg.186]

A mathematical model to be solved numerically has been developed and used to predict the separation effects caused by nonstationary conditions for a liquid membrane transport. Numerical calculations were made to compute pertraction characteristics such as input and output membrane selectivity (ratio of respective fluxes), concentration profiles for cations bound by a carrier in a liquid membrane phase, and the overall separation factors. These quantities are discussed as dependent... [Pg.379]

The above quantities are accessible by standard measurements of liquid membrane transport and are frequently reported in the corresponding literature. To emphasize the kinetic source of separations studied, all computations have been carried out after assuming the same equilibrium constants for cation-exchange reactions appearing in the pertraction system, i.e.. [Pg.384]

According to configuration definition, three groups of hquid membranes are usually considered (see Fig. 1.1) bulk (BLM), supported or immobilized (SLM or ILM), and emulsion (ELM) liquid membrane transport. Some authors add to these definitions polymeric inclusion membranes, gel membranes, dual module hollow-fiber membranes, but, to my opinion, the first two types are the modifications of the SLM and the third is the modification of BLM. It will be discussed in detail in the respective chapters. [Pg.4]

Many applications have been reviewed [5, 27, 68, 151—154]. The practical and theoretical aspects of SLM extraction from an analytical chemistry point of view are extensively presented therefore, they will not be described here. However, we would hke to present some examples to show that knowledge gained from basic studies on the liquid membrane transport can be utilized to solve practical problems in sample preparation. [Pg.115]

Tbe extraction of phenol has been used by Schlosser and Kossaczky11 and Halwachs et al.16 as a model for studying liquid-membrane transport. The former group compared the liquid-membrane method to a conventional liquid-liquid double extraction process. They concluded thet liquid membranes have disliact economic ndvsmages in cases where type I or type 2 facilitation methods can be used (e.g., phanel or metal ion extractions). However, where one must rely on simple differential permeation (bydrocarbon seperations) rhe ndvantage is less clear-cut. [Pg.846]
