Correlation between composition and properties of phosphate ester surfactants was exemplified by octyl phosphate with an optimum of foam inhibition and surfactant properties [301]. In separation and concentration of rare earth metals by liquid surfactant membranes 2-ethylhexylphosphonic acid mono-2-ethylhexyl ester was used as carrier [302]. [Pg.616]

Surfactant has a similar amphoteric structure as lipid, which makes it possible to form a stable membrane the same as a lipid membrane and can be used to embed proteins. A surfactant membrane has many characteristics similar to those of a biomembrane, so that it can retain the bioactivities of proteins well. The process of preparing a sur-factant/protein-modified electrode is simple and viable. There are usually two methods... [Pg.557]

In this paper we discuss results obtained in constructing the organized molecular systems for PET based on the use of ultrathin lipid or surfactant membranes, and in studying the mechanisms of PET in such systems. The state of the art in conjugation of PET across membranes with catalytic reactions of water reduction to dihydrogen and its oxidation to dioxygen will be also briefly discussed. [Pg.4]
