Analytical Chemistry of the Condensed Phosphates describes the concept and mode of operation of various analytical methods for analysis of the condensed phosphates. This book is composed of ten chapters, and begins with a presentation of the general properties of the condensed phosphates. Considerable chapters are devoted to various analytical techniques used for condensed phosphate analysis, such as gravimetry, titrimetry, and electrometric, chromatographic, physical, and automated methods. A chapter discusses the procedures for the determination of esters of the condensed phosphates. The concluding chapters survey the preferred method of quantitative analysis of these compounds, as well as the preparation of pure samples. This book will prove useful to analytical, inorganic, and organic chemists and researchers.
