Atomic Absorption Spectroscopy

The thoroughly revised new edition of this best-seller, presents the wide use of AAS in numerous fields of application. The comparison between the different AAS techniques enables the reader to find the best solution for his analytical problem. Authors Bernhard Welz and Michael Sperling have succeeded in finding a balance between theoretical fundamentals and practical applications. The new chapter 'physical fundamentals' describes the basic principles of AAS. The development of AAS is now described in a separate chapter. Further new chapters are devoted to the latest developments in the field of flow injection and the use of computers for laboratory automation. Methodological progress e. g. speciation analysis is also covered in this new edition. The index and the extensive bibliography make this book a unique source of information. It will prove useful not only for analytical chemists, out also spectroscopists in industry, institutes, and universities. Atomic Absorption Spectrometry will also be invaluable for clinics and research institutes in the fields of biochemistry, medicine, food technology, geology, metallurgy, petrochemistry, and mineralogy.

Atomic absorption spectroscopy is now a well-established technique for the determination of trace elements covering a wide range of analyte types. The early theory and instrumentation chapters incorporate recent trends in instrumental design and methodology, in particular those associated with electrothermal techniques and background correction. The major thrust of the book is represented by 14 application chapters which give an extensive well referenced review of the practical use of the technique written by experts drawn from their own speciality areas. These include the determination of trace elements in areas as diverse as environmental, chemical and industrial analysis. Whilst the book is primarily concerned with atomic absorption spectroscopy, any analyst involved in sample handling prior to trace elemental analysis will find this book a valuable compendium of methodology drawn from a very wide range of applications. For the current user of the technique the well referenced sections critically evaluate the state-of-the-art, while for the newer user the text will form the basis of a good laboratory handbook which offers a comprehensive instruction on the theory and instrumental design in atomic absorption spectroscopy.

Atomic Absorption Spectroscopy is an analytical technique used for the qualitative and quantitative determination of the elements present in different samples like food, nanomaterials, biomaterials, forensics, and industrial wastes. The main aim of this book is to cover all major topics which are required to equip scholars with the recent advancement in this field. The book is divided into 12 chapters with an emphasis on specific topics. The first two chapters introduce the reader to the subject, it's history, basic principles, instrumentation and sample preparation. Chapter 3 deals with the elemental profiling, functions, biochemistry and potential toxicity of metals, along with comparative techniques. Chapter 4 discusses the importance of sample preparation techniques with the focus on microextraction techniques. Keeping in view the importance of nanomaterials and refractory materials, chapters 5 and 6 highlight the ways to characterize these materials by using AAS. The interference effects between elements are explained in chapter 7. The characterizations of metals in food and biological samples have been given in chapters 8-11. Chapter 12 examines carbon capture and mineral storage with the analysis of metal contents.

This book describes both the theory of atomic spectroscopy and all the major atomic spectrometric techniques (AAS, Flame-AES, Plasma AES, AFS, and ICP-MS), including basic concepts, instrumentation and applications. Spectrochemical Analysis by Atomic Absorption and Emission is very wide in scope and will be extremely useful to both undergraduates and lecturers undertaking modern analytical chemistry courses. It contains many figures and tables which illuminate the text, covers various sample preparation methods and gives suggestions for further reading.

Analytical Chemistry, Second Edition, Volume 6: Atomic-Absorption Spectrophotometry focuses on the use of atomic absorption spectrophotometry as an analytical technique. This book discusses the developments in the analytical fields of atomic-absorption spectrophotometry. Organized into seven chapters, this edition starts with an overview of the fundamental principles underlying atomic-absorption spectra. This book then describes the use of high-temperature fuel-rich flames that allow the determination of some elements that were not previously capable of being determined by atomic-absorption spectrophotometry. Other chapters explore the advantages of improved instrumentation and consider the atomic-absorption procedures that have been applied to a wide variety of samples from agricultural and biological materials. This book discusses as well the determination of specified elements by a direct examination of the sample solution. The final chapter provides a list of instruments that are commercially available, with emphasis on their characteristics. This book is a valuable resource for analysts, physicists, and chemists.
