As implied by its title, this book attempts to introduce
the reader in a self-consistent fashion to the broad range
of electroanalytical techniques in common use. However, as
indicated by the author in his preface, it is not meant to
be used as a course textbook in the traditional sense. Rather
it employs an approach to which the author refers as "Open
Learning", which endeavors to make its content accessible
for self-study. Much of the material is presented in question-and-answer
format interspersed with exercises meant to enable the reader
to check his or her understanding along the way.
The first four chapters are devoted to traditional potentiometry
at solid electrodes, including an elementary treatment of
redox titration. The relationship of chemical activity to
analytical concentration is stressed throughout these chapters,
including a practical, though rudimentary, approach to estimating
and using activity coefficients. A short chapter on coulometry
is then employed as a bridge to two lengthy chapters on common
chronoamperometric methods, the first addressing primarily
experiments based on diffusion-controlled processes and the
latter a shallow treatment of rotating and flow systems. The
book ends with brief introductions to UV-vis and EPR spectroelectrochemistry,
impedance studies, computer simulation of electrochemical
processes, and some tips on electrode care.
The level of presentation is appropriate for the student
who has completed a traditional general chemistry sequence.
No physical chemistry and no quantitative analysis beyond
acid–base titration is assumed and, while several examples
involve organic analytes or other media, they are not essential
to a fundamental understanding of the material. Although a
handful of equations invoke differential calculus notation,
no understanding of calculus is actually required as the text
explains them in terms accessible to one with a high school
mastery of algebra. Theoretical underpinnings are almost exclusively
presented in the form of formulas without justification, and
the exercises offered merely invite the reader to "plug and
chug". No problems calling for reasoning skill and no instructions
or outlines for practical laboratory procedures are provided.
In addition to the inevitable occasional typographical error
and several graphs that don't quite match their textual descriptions,
the reader must contend with a distinctly British usage and
nomenclature. This is certainly not impossible to manage,
but could lead to some head-scratching for the student new
to these techniques. There is also a curious penchant for
certain less-than-common IUPAC units. Analytical concentrations
specified in moles per cubic decimeter take some getting used
to.
While it's conceivable that this book could be used as a
text in an undergraduate course involving electroanalytical
chemistry, its shallow treatment and unusual presentation
make it awkward for that purpose. Similarly, it is probably
not ideal as a general reference, although the handful of
citations of current books and review articles on aspects
of electrochemistry might serve to point one toward more comprehensive
treatments. In all fairness, the author alerts us to this
possibility up front. On the other hand, for the student who
needs to become conversant in electroanalytical methods without
benefit of a formal course (for example, if he or she wished
to attempt an undergraduate research project involving an
electrochemical method prior to being qualified to enroll
in an instrumental analysis course) the traditional offerings
are typically either narrowly focused or overwhelming for
self-study by all but the most stalwart neophyte. This book
provides a compact and reader-friendly treatment that makes
modest demands in terms of preparation, yet leaves the reader
with a broad, if not particularly deep, foundation of understanding
to which may then be added the details particular to the matter
at hand.
