There are few really satisfactory methods of analysis for tungsten, as this monograph with its multitudes of alternative procedures bears witness. The volumes of the Handbuch tend to be comprehensive rather than critical, and this one is no exception. After a brief introduction, the material is organized under the headings: sample preparation, separation methods, gravimetry, titrimetry, photometry, spectral analysis, atomic absorption spectrometry, fluorimetry, polarimetry, catalyti~lectrometric methods, thermal analysis, activation analysis, x-ray fluorescence, other methods (x-ray and mass spectrometry and gas chromatography) and finally methods for the investigation of particular tungsten compounds. The literature is covered exhaustively from 1942 to the beginning of 1976 with suitable reference to standard texts for earlier work. Practical details are given as well as explanatory information. The book is written in German; it is certainly an essential text for all who require methods of analysis for tungsten and tungsten-bearing materials.
J. W. Price and R. Smith, Tin (W. Fresenius, Ed., Handbuch der analytischen Chemie, TeiZ3, Band 4ay;), Springer-Verlag, Berlin-Heidelberg, 1978, xi + 262 pp., price DM 146.00, $73.00. The cover of this volume of the Handbuch bears an uncompromising Zinn. The English-speaking reader therefore receives a pleasant surprise on opening the book to find that the whole thing is in English. The material is organized according to the normal pattern: chapters are devoted to detection, gravimetry, titrimetry, photometry ,electroanalysis, extraction, atomic absorption spectrometry, emission spectrometry, x-ray fluorescence, and activation and Mossbauer methods; the subsequent ten chapters deal with analytical methods for tin-bearing materials, from ores to organotin compounds_ Unlike most other volumes in the Handbuch, this text makes no claim to be comprehensive. It is, however, written with authority, the authors having drawn widely from their own industrial experience. The literature coverage is quite good, with occasional references to 1974-75, but the 1979 reference (p. 172) is a printing error. Though it is different in nature, this volume is well worthy to stand beside the others in this excellent Handbuch. Some readers will miss the detailed yet concise information on perhaps rather obscure methods which allows a personal opinion to be reached on the viability of a method without recourse to the original literature; others will welcome the fact that the initial selection process has already been done. Whichever way one looks at it, this volume remains essential reading for analytical chemists concerned with tin. The German readers’ loss is undoubtedly the English readers’ gain, and it is to be hoped that this venture into English will encourage new readers to delve further into the many useful volumes of the FreseniusJander Handbuch-
