Analytical Chemistry of Organic Halogen Compounds presents the procedures applied in the analysis of organic halogen compounds. This book is composed of eight chapters that discuss the methods involved in the production and application of organic halogen compounds and in overcoming contamination problems caused by these compounds. After briefly dealing with the preparation, characteristics, and reactions of organic halogen compounds, this book goes on discussing the fundamental concepts of methods for the detection of halogens in organic compounds, namely, chlorine, bromine, iodine, and fluorine. The following chapter describes the characteristic features, advantages, and disadvantages of ultramicro and submicro chemical methods. A chapter also examines the qualitative and quantitative studies of organic halogen compounds based on the thermal and chemical stability of these compounds. The concluding chapters discuss the interference or interfering effects of halogens and their elimination in the determination of other elements. A list of physical constants of organic halogen compounds of general pharmaceutical and industrial significance is provided. This book is an ideal source for analytical chemists and other workers who are interested in the theoretical bases of the methods.




The Destruction of Organic Matter


Book Description

International Series of Monographs in Analytical Chemistry, Volume 39: The Destruction of Organic Matter focuses on the identification of trace elements in organic compounds. The monograph first offers information on the processes involved in the determination of trace elements in organic matters, as well as the methods not involving complete destruction of these elements. The text surveys the sources of errors in the processes responsible in pinpointing elements in organic compounds. These processes include sampling, disruption of the samples, manipulation, and measurements. The book examines the processes of wet and dry oxidation, including their applications to sulfuric, nitric, and perchloric acids and hydrogen peroxide. The methods of dry ashing and oxidation with excited oxygen and oxidative fusion are elaborated. The text also underscores the varying methods in removing trace elements in organic compounds. The elements include zinc, copper, silver, gold, lead, germanium, titanium, arsenic, bismuth, and vanadium. The book also describes wet digestion methods and dry ashing procedures in the removal of trace elements in organic matters. The monograph is a vital source of information for readers interested in the identification of trace elements in organic compounds.




Enzymatic Methods of Analysis


Book Description

Enzymatic Methods of Analysis attempts to cover all the aspects of modern enzymatic analysis. Enzymes possess a great potential usefulness in analytical chemistry. The specificity of enzymes can solve the primary problem of most analytical chemists—the analysis of one substance in the presence of many similar compounds that interfere in the analysis. The book begins with two introductory chapters devoted to general considerations of enzymes as reagents and methods of analysis of enzymatic reactions. The next four chapters deal with methods for the assay of specific enzymes, and substrate, activator, and inhibitor analysis using enzymes. In the last two chapters the immobilization of enzymes and the automation of enzymatic reactions are discussed. In addition, a listing of all commercially available enzymes is given in an appendix. It is hoped that the information presented will prove interesting and stimulating to all individuals engaged in research and development.




Substoichiometry in Radiochemical Analysis
