aspects is provided by the final chapter, Transformation
in the Reactor. This chapter describes the technical execution of reactions particularly with respect to transport
phenomena and selectivity. The chapter ends with a discussion of the optimum catalyst.
The book is clearly written rind readable throughout. In
view of the abundance of facts and the clear presentation,
it is to be hoped that it will be of use not only to students
but also to chemists in research and industry.

Ausgewahlte Methoden der Wasseruntersuchung. (Selected
Methods of Water Investigation). Vol. I . Published by
the lnstitut fur Wasserwirtschaft, Berlin. VEB Gustav
Fischer Verlag, Jena 197 1. 1st ed.. xv, 250 pp., 6 figures.
6 tables, loose leaf volume DM 29.--.
This collection of water investigation methods written by
a group of authors under the editorship of Chrisra Lcylcr
is based mainly on expcrience in the laboratories of water
authorities, health establishments, and polytechnics in the
member countries of the Council for Mutual Cooperative
Association. The first part, which comprises about 40 system numbers, is to be supplemented by two others at
intervals of about one year each.
The classification of the subject matter follows well-known
patterns, and is based on the nat~ireof the substances
present in the water, e. 9.. dissolved gases, cations, anions,
organic substances, t’tc. The authors’ approval of wellknown works in the literature can also be seen in the
treatment of the objects of investigation. A brief introduction is followed by sections on special sampling, preservation of the sample, qualitative and quantitative determination, range of application of the method, possible sources
of interference and their elimination, equipment and chemicals required, investigation procedure, calculation. and
expression and rounding-off of the results.
Corresponding to the importance of sampling, a general,
very detailed section is first devoted to this topic. Special
emphasis is placed, inter aliu, on the detailed indication
of preservatives where sampling and examination are separated by a period i n which changes in the substances contained in the water could occur.
I t remains to bc seen whether all the data in this section
will survive the results of more recent and still current
investigations. Doubts are certainly in order when one
reads about “very mild preservation” by storage of the
watcr sample in the dark at 1 to 3.C with..no refcrcnce
to the extremely effective method of deep freezing.
The principal methods discussed in this first part include
those for the determination of iron. manganese, and mercury ions, cyanide phosphate, and silicate ions, the biochemical and chemical oxygen demands, and phenols and
surfactants: for these methods the literature has been
covered in part up to 1970, but the last five years appear
to have been overlooked in places.
The presentation is generally clear and easy to grasp;
in places, however, both in the wording of the text and
in the reproduction of physical quantities and equations,
one misses the exactness that is to be expected and that
is in fact found on other pages. However, this critical
observation can in no way detract from the value of the
part that has appeared so far, but should encourage the
team of authors to pay due attention to the “externals”
in future parts.

Selective Ion Sensitive Electrodes. By G . J . Moudj. and
J . D. Thoriias. Merrow Publ. Co. Ltd., Watford 1971.
1st ed., vii. 140 pp.. numerous figures, bound f 2.15.
The booklet under review very strongly stresses the
practical use of ion-selective electrodes. Thus there
is a distinct emphasis on the assessment of parameters
of the various types of electrodes, which are divided into
glass electrodes and homogeneous and heterogeneous solid
and liquid membrane electrodes. The discussion deals particularly with the selectivity of the electrodes (with the
methods for its determination), speed of response, e.m.f.
stability, reproducibility, life, detection limits, and general
construction. Valuable hints on the calibration of the electrodes and their effective practical use are also given. A
particularly useful feature is the remarkably objective
assessment of a series of commercial ion-selective electrodes. which is documented by numerous tables and illustrations and has been partly supplemented by the authors’
measurements.
The theoretical trcatrnent of the membrane phenomena
and their practical consequences are somewhat oversimplified in places, or are even totally absent; minor
shortcomings (cf. e.g. Fig. 29) occasionally cali for some
additional thought on the reader’s part.
Nevertheless, the book can be rccommended strongly and
without reservations to all those who have to use ion-selective sensors in analytical practice.
