treat the practical application of inorganic membranes in selected technically relevant examples. A comparison of the performance of polymeric and inorganic membranes as given in Chapter 8 is problematic because of different operating conditions and product costs. It does, however, give some hints where the authors see the advantages of inorganic membranes over polymeric products. The list of inorganic membrane manufacturers given in the appendix of the book is quite useful, but it might be very soon outdated in a rapidly growing and changing market. Overall, the book gives a comprehensive view of the state-of-the-art of inorganic membranes, including their preparation and application. It is equally suited for scientists and engineers as for students who want an easy-to-understand and application-oriented introduction to the technology of inorganic membranes. It is reasonably well balanced covering the most relevant aspects in sufficient depth. H. STRATHMANN
Polymers for Gas Separation by Naoki Toshima (ed.); published by VCH-Verlagsgesellschaft, Weinheim/New York/Basel/Cambridge, 1992; 245 pp.; price DM156.00 or 658.00. The separation, concentration and purification of gases and vapours is considered as one of the important future industrial applications of synthetic polymeric membranes, and during the last two decades substantial effort has been concentrated on the development of membranes with satisfactory mass-transport properties for specific gas separation problems. This recent work is described in a large number of detailed publications and patent applications. However, very few review-type articles or books have been published to date that cover the most relevant aspects of membrane gas separation comprehensively and in sufficient depth.
This book provides not only a good introduction for scientists and engineers interested in the basic concepts related to the use of membranes in gas and vapour separation, but it is equally suited as a reference book for those already familiar with the field who would like to be informed about recent developments. In seven chapters totalling about 240 pages, all major aspects relevant to the development of efficient gas-separation membranes are covered comprehensively. The book is well balanced in its content and surprisingly uniform in nomenclature and general structure, considering that the various contributions have been written by ten different authors. The first chapter, by N. Toshima, provides a very brief introduction to the field of membranes in gas separation, stressing technical needs and commercial relevance. In the second chapter, written by S. Kimura and T. Hirose, some fundamental relations concerning the gas-transport mechanism in polymeric material as well as some engineering parameters determining the design of gas-separation processes are discussed. Although the chapter is kept rather brief, most of the relevant aspects are covered in sufficient depth. The relationships between the aggregation state of polymers and their gas-permeation properties are discussed in some detail in the third chapter, written by T. Kajiyama. This discussion provides the basis for the subject treated in the next chapter by H. Odani and T. Masuda in their contribution on designing tailor-made polymeric membranes for specific gas-separation tasks. The facilitated gas transport via selective carrier components which are immobilized either as a liquid in a porous polymer structure as so-called supported liquid membranes, or as fixed carriers bound to the polymer matrix is discussed in Chapters 5 and 6 by N. Toshima and H. Asanuma and H. Nishide and E. Tsuchida. The last chapter, written by H. Hirai, is devoted to the separation of carbon monoxide from ethylene by absorption in polymers containing specific functional complexes. Overall, the book gives a comprehensive introduction to the field of gas separation by semi-permeable polymeric membranes. It treats the basic concept of the process as well as recent new developments. It can be recommended as a useful text and reference book, not only to scientists and engineers or students interested in obtaining a selective complete overview but also to those already active in the field but interested in recent developments, especially in Japan, and possible future developments.
