Water Analysis, Volume III: Organic Species is a seven-chapter text that emphasizes the methods used for the determination and analysis of organic constituents in both natural and polluted waters. Chapters 1 and 2 deal with waste strength and waste pollution parameters of a nonspecific variety, such as biochemical oxygen demand, chemical oxygen demand, total organic carbon, spectroscopic measurements, electrochemical methods, and a number of other techniques that provide chemical class determinations. Chapter 3 provides the current methods for isolating, concentrating, and partitioning organic constituents from water. Chapter 4 examines gas chromatographic separations and analyses and capillary and packed-column techniques. This chapter also presents injector techniques, derivatizations, detector types, qualitative and quantitative analyses, and a representative list of applications. Chapter 5 discusses the principles of organic mass spectrometry, mass analysis, ion detection, chromatography/mass spectrometry, tandem mass spectrometry, qualitative and quantitative analysis, and selected applications. Chapter 6 describes the principles and applications of using high performance liquid chromatography for water analyses, as well as the necessary equipment, the chromatographic process, and practical use and optimization of the method. Chapter 7 covers the use of infrared spectrophotometry for analyzing for organic pollutants in water, considering both theoretical aspects and practical applications of this technique.
