Instrumental Methods for Determining Elements reviews and compares the most commonly used instrumental methods of elemental analysis, including atomic absorption and emission spectrometry, electrochemistry, potentiometry, chromatography, x-ray fluorescence, and combustion techniques. A brief introduction to the theory of these techniques is presented along with the factors that are important in selecting the proper technique for an application. Advantages and limitations of each instrumental method are detailed enabling the analyst to compare different techniques before choosing the most reliable and cost effective technique for their needs. Because of the wide variety of choices in the available instrumentation to perform various types of analyses, Instrumental Methods for Determining Elements is an essential resource for analytical chemists and chemical engineers who need to decide which method to use or which instrumentation to purchase.

The analysis of materials containing several elements used to be a difficult problem for analytical chemists, so a well established sequence of wet chemical qualitative tests were performed to ensure each element was detected. Quantitative tests could then be carried out on the sample, according to the range of elements present. Most analytical chemists were very familiar with these techniques, having been taugth them from a very early stage in their education and careers. The analytical chemist can now call on a range of specialist instrumental techniques which can detect the presence of many elements, often simultaneously, and often quantitatively, providing rapid results on samples which, in the past, could take days. The drawback is that the instruments tend to be expensive, suited to particular sample types or matrices and complex in both setting up and in the interpretation of results. Furthermore the general analytical chemist may have access and familiarity with only one or two methods. Written by an international team of contributors, each experts in their particular fields, this book familiarizes analytical chemists with the range of elemental analysis techniquers, to enable them to specify the most appropriate test for any given sample. In addition, it contains important chapters on sample preparation and quality control, essential elements in obtaining accurate and reliable analytical results. As such, this book will be essential reading for all analytical chemists. The techniques of elemental analysis are important in many other disciplines, so the book will be of particular interest to those commissioning a wide range of analytical measurements, such as chemists, geologists, environmental scientists and biologists. The breadth and depth of coverage will also make the book very useful for advanced students.

Analytical chemistry has been important since the early days of chemistry, providing methods for determining which elements and chemicals are present in the object in question. During this period significant contributions to analytical chemistry include the development of systematic elemental analysis by Justus von Liebig and systematized organic analysis based on the specific reactions of functional groups. The first instrumental analysis was flame emissive spectrometry developed by Robert Bunsen and Gustav Kirchhoff who discovered rubidium (Rb) and caesium (Cs) in 1860. Written for a course that deals with the principles and applications of modern analytical instruments. Emphasis is placed upon the theoretical basis of each type of instrument, its optimal area of application, its sensitivity, its precision, and its limitations. The book also introduces students to elementary integrated circuitry, microprocessors and computers, and treatment of analytical data.

The knowledge of metal ion speciation is essential for predicting the exact toxicities of metal ion species in the environment. Metal ions can exist in various oxidation states, each of which possesses different physical and chemical properties as well as exhibit varying toxicities. Often, toxicity data is unreliable because it is based on metal io
