part of the reader, especially for complicated reaction equations. These general formulations (e.g. where diffusion and
penetration overpotentials are present simultaneously in a
reaction with several steps) are made specific to particular
situations depending on which is the rate-determining step in
the reaction. It would have been desirable to illustrate the
relevance of these distinctions for practical situations by giving more examples.
Whereas the fundamentals of metal dissolution are treated
in great detail, the dependence of the kinetics of dissolution
on the microstructure of the metal surface is unfortunately
not discussed. This fails to take account of recent findings
that the inhomogeneous nature of real surfaces (points where
dislocations meet the surface, grain boundaries, semicrystalline regions, etc.) has crucial effects on the kinetics of
metal dissolution. The experimental techniques using rotating disk or disk-and-ring electrodes which are important in
electrochemical investigations are thoroughly described. In
contrast, however, the various mechanisms of iron dissolution are treated only briefly in relation to their importance,
despite the fact that a great deal of detailed work on this
topic has been published.
The chapters on the passivity of metals and their transpassive dissolution are well and clearly written. It would also
have been of interest to include a more detailed discussion of
the effects which the build-up of the passive layer has on the
kinetics of dissolution. Treating the transpassivity of metals
together with the occurrence of pitting corrosion (p. 173) is
of doubtful value, as the two mechanisms are fundamentally
unrelated. It would have been better to have included a separate chapter on the kinetics of pitting corrosion.
The final chapter describes the application of kinetics to
corrosion calculations, well illustrated by figures. Here again
it becomes necessary to distinguish between a number of
different cases, showing, for example, the influence of the
oxidizing medium or of diffusion processes on calculations
of the corrosion current o r of the free corrosion potential.
The author illustrates very well the usefulness of the polarization resistance for determining corrosion rates, and also
details the sort of errors that can arise when the anodic or
cathodic partial reactions are no longer controlled purely by
ion penetration. The discussion of the different possible
types of corrosion protection turns out to be rather brief;
however, the book does not set out to cover this topic.
To summarize, this book discusses all aspects of electrode
kinetics that are important in the dissolution of pure undeformed metals. Readers who already have some previous
knowledge of corrosion will find here a very useful introduction to the kinetics of metal dissolution, a topic which is not
covered in such detail in mainstream books in the field.

The physical chemistry of surfactant solutions is a topic
which continues to attract increasing attention. For this reason the appearance of new textbooks aimed at enabling the
reader to enter this field is not unexpected.
In the book reviewed here the author has succeeded well in
that aim. The easily readable English text is concisely written, and helps towards a sound understanding of the phenomena described. Although it is not clear why the word
“technology” appears in the title, this is, in fact, a good
textbook which contains 466 literature references and a bibliography listing 35 books.
The contents are arranged in eight chapters on the following subjects: Overview; The Organic Chemistry of S u r f x tants; Micellization; Solubilization, Microemulsions and
Micellar Catalysis; Surface Activity and the Liquid/Vapor
Interface; Emulsions; Foams ; Surfactants at the Solid/
Liquid Interface.
An exhaustive coverage is not to be expected of a textbook. Thus, for example, rheology is not included at all, and
consequently viscoelastic solutions and gels are not treated.
Also the phase behavior at the inversion point is not explained in accordance with the most recent findings.
The quality of the book stands out above that of many
rapidly produced publications, and it should achieve a wide
