Available in PDF, EPUB and Kindle. Book excerpt: Organic contaminants at concentrations of parts per billion or less may modify water quality significantly. However, even the most sensitive of the available analytical procedures are not capable of quantitative identification at these trace levels. Thus, the organics must be concentrated prior to analyses. Freezing was evaluated as a concentration technique. As solute-containing aqueous solutions are frozen, the ice which crystallizes initially is very pure. The solutes are rejected into the unfrozen liquid. If the process is interrupted prior to complete solidification, the residual liquid will be considerably enriched.

Available in PDF, EPUB and Kindle. Book excerpt: Water Pollution Research covers the proceedings of the Eighth International Conference on Water Pollution Research, held in Sydney, Australia on October 17-22, 1976. This book is composed of 150 and begins with discussions of the different sources of water pollution, including aerosolization, viral contamination, hydrocarbons, and heavy metals. Considerable chapters are devoted to various chemical processes for wastewater management; technical requirements for standard water quality; and methods of pollutant analysis. These topics are followed by surveys of Sydney's design of ocean outfall, an integrated pollution control system, and sewage sludge disposal. Other chapters describe the features of wastewater treatment reactors and other treatment alternatives. The remaining chapters present various case studies demonstrating the performance and improvements of different wastewater treatment facilities. This book will prove useful to water pollution researchers, environmentalists, and design engineers.
Download or read book Recovery of Trace Organic Pollutants by Solvent Extraction and Freeze Concentration written by William Chih-Wen Chang and published by . This book was released on 1970 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The objective of this investigation was to evaluate the use of batch type solvent extraction and freeze concentration in recovering trace organic pollutants from water. The work was performed using a simplified water system containing known concentrations of phenol, and natural water systems collected from three sources (Meramec Spring, Gasconade River near Jerome, and Missouri River in Jefferson City) with different levels of pollution. The simplified water system was used to evaluate the effect of the number of extractions, solvent to sample ratio, extraction time, initial organic concentration, pH, and turbidity on solvent extraction; and the effect of volumetric concentration and flash freezing on freeze concentration. The natural water systems were employed to evaluate the practical application of the method, and emphasis was placed on the selection and sequence of solvents, pH adjustment, and effect of turbidity. Benzene and chloroform were the solvents used. The proper selection of solvents and the solvent to sample ratio were the most important factors in the solvent extraction method; the number of sequential extractions and pH adjustment were also important variables. Serial extraction with chloroform and benzene yielded a larger recovery at natural pH than extraction with benzene and chloroform; and extraction with chloroform sequentially at pH 4 and 10 produced a greater recovery than extraction with benzene. The concentration of trace organics in spring and river water was subject to significant seasonal variation. The efficiency of phenol recovery by freeze concentration depended on the volumetric concentration ratio and almost complete recovery was obtained at ratios ranging from 6 to 9"--Abstract, leaf ii.

Book excerpt: 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.
