Book Description
The analysis of solid materials by introducing solid test sampies directly into the graphite furnace of an atomic absorption spectrometer must be regarded as a powerful analytical approach. Even if it is - of course - not the "ultimate method". After three decades of development, the instrumentation and the methodology are available to apply solid sampling successfully for the analysis of almost every material. Moreover, several tasks cannot be solved using other analytical methods as neatly as they can using direct solid sampling. The conventional methods work more or less satisfactorily, so why do we sug gest applying solid sampling much more extensively than it is today? To begin with, the features pointed out time and again should be named: Rapidity of the analytical procedure, low susceptibility to analyte loss or contamination, very smallquantities can be analyzed, and expenditure on instrumentation and per sonell is also low. These properties are examined and the necessary conditions are discussed (Chapter 1) as are the analytical tasks (Chapter 6) for which use of this method is advantageous. Other features that are often overlooked are just as important: The simplicity of the analytical procedures allows the analyst to main tain an intimate relationship with the original scientific task that has to be solved with the analysis. Furthermore, the considerable reduction of working place haz ards and pollution by avoiding the use of chemical reagents must nowadays be assessed as a feature as important as the others.

Book Description
The first edition of our Handbook was written in 1983. In the preface to the first edition we noted the rapid development of inductively coupled plasma atomic emission spectrometry and its considerable potential for elemental analysis. The intervening five years have seen a substantial growth in ICP applications; much has happened and this is an appropriate time to present a revised edition. The basic approach of the book remains the same. This is a handbook, addressed to the user of the technique who seeks direct, practical advice. A concise summary of the technique is attempted. Detailed, theoretical treatment of the background to the method is not covered. We have, however, thoroughly revised much of the text, and new chapters have been added. These reflect the changes and progress in recent years. We are grateful to Mr Stephen Walton, Dr Gwendy Hall and London and Scandinavian Metallurgical Co. Ltd for their contributions. Chapter 3 (Instrumentation) has been rewritten by Mr Walton, the new Chapter on ICP-mass spectrometry has been written by Dr Hall, and London and Scandinavian provided much of the information for the chapter on metals analysis by ICP-AES. These chapters have been integrated into the book, and a conscious effort has been made to retain the unity of style within the book. New material has been added elsewhere in the book, archaeological materials are considered, pre concentration methods and chemometrics covered more fully.

Book Description
Trace metals occur as natural constituents of the earth's crust, and are ever present constituents of soils, natural waters and living matter. The biological significance of this disparate assemblage of elements has gradually been uncovered during the twentieth century; the resultant picture is one of ever-increasing complexity. Several of these elements have been demonstrated to be essential to the functions of living organisms, others appear to only interact with living matter in a toxic manner, whilst an ever-decreasing number do not fall conveniently into either category. When the interactions between trace metals and plants are considered, one must take full account of the known chemical properties of each element. Consideration must be given to differences in chemical reactivity, solubility and to interactions with other inorganic and organic molecules. A clear understanding of the basic chemical properties of an element of interest is an essential pre-requisite to any subsequent consideration of its biological significance. Due consideration to basic chemical considerations is a theme which runs through the collection of chapters in both volumes.

Book Description
The IAEA has compiled this overview of current applications of nuclear analytical techniques (NATs). The contributions included in this book describe a variety of nuclear techniques and applications, such as those in the fields of environment and health, industrial processes, non-destructive testing, forensic and archaeological investigations, cosmochemistry and method validation. The techniques covered range from classical instrumental neutron activation analysis (INAA), its radiochemical derivative RNAA, in-beam methods such as prompt y neutron activation analysis (PGNAA) and accelerator mass spectrometry (AMS), to X ray fluorescence (XRF) and proton induced X ray emission (PIXE) spectroscopy. Isotopic techniques to investigate element behaviour in biology and medicine, and also to validate other non-nuclear analytical techniques, are described. Destructive and non-destructiveapproaches are presented, along with their use to investigate very small and very large samples, archaeological samples and extraterrestrial samples. Several nuclear analytical applications in industry are described that have considerable socioeconomic impact wherever they can be implemented.

Book Description
"Heavy Metals: Problems and Solutions" is divided into three sections dealing with basic geochemical processes, remediation and case studies. The basic geochemical processes are discussed with respect to mobility in the environment and impact as well as methods to derive guidelines for heavy metals. Remediation focuses on currently available methods to treat contaminated sediments and soils. In addition, it considers the concept of geochemical engineering for remediation of large areas contaminated by metals. A number of case studies of polluted sediments and soils and their environmental impact highlight the principles discussed in the first two sections.

Book Description
Microwave-Assisted Sample Preparation for Trace Element Analysis, Second Edition, describes the principles, equipment, and applications involved in sample preparation with microwaves for detecting and analyzing trace elements. Hot topics such as sample preparation for speciation, metabolomics, and halogen determination, as well as the alternatives of sample preparation for special samples (for example, carbon nanotubes, polymers, petroleum products), are also discussed. This completely updated second edition covers all the new devices and more powerful systems that have emerged in the last several years, such as Ultrawave and Ultraclave systems. New challenges in the fields of geology, environmental and biological studies -for example, the need for further determination of rare earth elements and halogens - are currently only covered in scientific journals and not in a comprehensive way. This book offers a summary of the state-of-the-art ways to meet these challenges with microwave-assisted sample preparation. The only book to cover in depth the principles, equipment, and applications of microwave-assisted sample preparation Written by experts in the field who provide a comprehensive overview of the important concepts Introduces the latest devices and systems used for in microwave-assisted techniques, including Ultrawave and Ultraclave systems

Book Description
Metal recycling is a complex business that is becoming increasingly difficult! Recycling started long ago, when people realized that it was more resource- and cost-efficient than just throwing away the resources and starting all over again. In this report, we discuss how to increase metal-recycling rates - and thus resource efficiency - from both quantity and quality viewpoints. The discussion is based on data about recycling input, and the technological infrastructure and worldwide economic realities of recycling. Decision-makers set increasingly ambitious targets for recycling, but far too much valuable metal today is lost because of the imperfect collection of end-of-life (EoL) products, improper practices, or structural deficiencies within the recycling chain, which hinder achieving our goals of high resource efficiency and resource security, and of better recycling rates.
