Metal transport phases for iron, manganese, copper, cadmium, and lead are shown in Figures 10-14, with individual elemental data given in Tables VIll and IX. The fractionation scheme was applied to composite samples for Sites 1 and 2, and all fractionations were performed in duplicate. [Pg.164]

The primary reason for employing vapor-phase or neutralizing amines in steam-condensate systems is to reduce the level of corrosion of both ferrous and nonferrous metals. A further beneficial consequence of this function is the reduction of metal transported back to the FW system. [Pg.534]

It is also known that metal transport can be initiated by interactions between gas-phase molecular species rather than free radicals and solid metals (Section II.D). [Pg.407]

Kirch and Lehn have studied selective alkali metal transport through a liquid membrane using [2.2.2], [3.2.2], [3.3.3], and [2.2.C8] (146, 150). Various cryptated alkali metal picrates were transported from an in to an out aqueous phase through a bulk liquid chloroform membrane. While carrier cation pairs which form very stable complexes display efficient extraction of the salt into the organic phase, the relative rates of cation transport were not proportional to extraction efficiency and complex stability (in contrast to antibiotic-mediated transport across a bulk liquid membrane). Thus it is [2.2.Ca] which functions as a specific potassium ion carrier, while [2.2.2] is a specific potassium ion receptor (Table VI). [Pg.22]

Three reviews of chiral molecules have appeared.52,53,26 The first of these discusses using 7r contacts from supported metal complexes to separate enantiomers by GC and HPLC.52 The second is useful to those reading Portugese.53 The third addresses changing the transport phase affinity of chiral enantiomers by adding chiral additives such as cyclodextrin or a chiral metal complex that form second-sphere contacts in the mobile phase.26... [Pg.569]

In these representations, the electron-transporting phase is usually a metal however, in certain cases it can be an electron-conducting oxide, other compound, or other material, such as graphite. Furthermore, two categories of electron-transporting phases may be encountered ... [Pg.41]
