book is not entirely satisfactory, it will nevertheless be a great
help to the specialist in the vitamin field provided he exercises
caution in its use.

For decades, “Die physikalische Chemie der Silicate” (The
Physical Chemistry of Silicates) by W. Eitel was the standard
textbook in the field of silicate chemistry. It appeared in
several German editions and finally in a n English edition in
1954. In the meantime, the results of experimental studies of
silicates have assumed unprecedented dimensions : over 20000
publications have appeared within the past 15 years alone!
In his new work, “Silicate Science”, the author attempts
to catch up o n this lag in reviews of original publications. The
present volume is the first of a planned series of five.
Chapters 1-3 correspond to the content of his older monograph and contain a general description of the Si-0 bond
together with a survey of the crystal structures of silicates,
with particular emphasis on isomorphic and isotypical
relationships t o non-silicate systems. Epitaxic phenomena
are also dealt with. The systematic classification is built up
on the Bragg system and its supplementation by Zoltai;
however, the work of Below and his school is also given due
attention. The second section is devoted to clay minerals,
particularly their structures. In the last section, which makes
up over half the book, the problems of colloid chemistry and
the surface properties involved in silicate chemistry are
discussed. In this connection, aluminum oxide/silicon dioxide
gels and cracking catalysts are described.
methods. However, some methods which might have been
preferred by experienced analysts have been omitted. For
some elements, several practical procedures are described in
detail, but for others, little more than short headings and
literature references are given. For the sections o n the
separation of the elements, this abbreviated style has been
used throughout. Occasionally only a literature reference is
given for the examination of some natural and synthetic
products.
The vast number of literature references given, which are
mostly linked with a condensed description of the content of
the papers concerned, is the best feature of this book. Some
parts could have been improved by more careful editing.
Although the book has little hope of ousting the established
works on photometric analysis, it is valuable, particularly
because of its second section, for rapid reference to the
solution to certain problems. H . B ~ & [NB 358p16 IE]

Colorimetric Determination of Elements. Principles and
Methods. By G. Chnrlot. Elsevier Publishing Co., Amsterdam-London-New York 1964. 1st edit., I X
449 pp.,
72 figs., 12 tables, linen D M 56.- (about $ 14.-).
This monograph reviews the current status of knowledge of
the spectroscopy and photochemistry of hexavalent uranium.
Chapter 1 deals with the spectroscopy of solid uranyl salts.
Following a n introductory section o n the structure of
crystalline uranyl compounds, discussions are given on their
fluorescence, absorption, and infrared spectra. Chapter 2
deals with the spectroscopy of uranyl compounds in solution.
Chapter 3 describes the intensity and decay of uranyl Auorescence and Chapter 4 the photochemistry of uranyl compounds, while Chapter 5 gives a short presentation of the
theory of the electronic structure of the uranyl ion.
The material is presented mainly in chronological order
within each section. The main contributions are naturally
derived from publications which appeared after 1940. A
practically complete list of references is given for the literature
from 1833 (!) to 1961; work that appeared after completion
of the manuscripts is listed in a n appendix covering publications up to the end of 1963.
Naturally, monographs of this type appeal to only a very
limited readership. However, they usually are indispensible
aids for the experts in their specific fields, and this is particularly true of the present volume. All associated with the
chemistry and especially with the spectroscopy of uranium
or of actinides in general will be grateful to the authors for
their efforts in compiling this book.

This book is in the main a translation of the second French
editionof 1961, afewsections having been revised bytheauthor.
In the general section (154 pp.) - somewhat inaptly entitled
“Theoretical Background” - Beer’s law and the fundamentals
of the techniques and equipment used in photometry,
fluorimetry, turbidimetry, and nephelometry are discussed.
The general physical principles aredealt with only summarily;
details concerning apparatus are not given. O n the other
hand, the author goes further into the sources of error and
accuracy of photometric estimations, but again practical
aspects are dealt with less thoroughly than the formal
mathematical concepts. This section also includes chapters
on extraction, ion exchange, chromatography, separations
via the gas phase (11/2 pages and 2 tables), and electrolytic
processes. Although it must be admitted that separations are
often intimately connected with photometric estimations, a
general reference to paper chromatography and ion-exchange
chromatography on about 1 page each are useful only to
readers who are totally unfamiliar with these processes. The
section on the separation of traces (2 pp.) is also poor. In the
second section (280 pp.), procedures for determining 65
elements are described; these are all reliable, well tested
Inorganic Ion Exchangers. By C. B . Amphlett. Topics in
Inorganic and General Chemistry. Edited by P . L. Robinson. Monograph 2. Elsevier Publishing Co., ArnsterdamLondon-New York 1964. 1st. edit., XI + 141 pp., 36 figs.,
32 tables, linen about DM 23.- (about S 5.50).
This book has appeared as the second volume of a large series
of individual monographs on inorganic and general chemistry. The use of inorganic ion exchangers has acquired
increasing importance in recent years on account of their high
thermal stability and resistance to radiation.
After a short historical introduction and a general survey, ion
exchange on clay minerals, zeolites, and salts of heteropolyacids are dealt with. The major portion of the book is devoted
to the exchange properties of zirconium phosphates and
related compounds, on which the author has done a considerable amount of research. The exchange equilibria, ion separations and selectivities, suitability for water purification, and the
preparation of ion-exchange membranes are discussed for
zirconium phosphates. Despite the condensed nature of the
text, the author has succeeded in illuminating the problems
The author has managed to review the vast literature in this
field in magnificent fashion. It should be emphasized that in
all chapters, whenever the views of different research groups
d o not concur, the different experimental methods and interpretations are presented together. The reader thus has the
opportunity of appraising the arguments for himself. For
this reason, the book offers a summary of information that
is valuable not only for those who wish to acquaint themselves with special topics of this subject but also for experts
in this field. It deserves a place in every chemical library.
However, it does not provide a modern textbook of silicate
chemistry, which is still lacking.
