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.

This book was released on 2020-04-07 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: New Generation Green Solvents for Separation and Preconcentration of Organic and Inorganic Species is designed to help researchers and students understand the production and application of new generation green solvents in separation- and preconcentration-based analytical methods. Beginning with the historical background and milestones in the development of analytical instrumentation, the book goes on to give a detailed overview of the most up-to-date uses of green solvents in sample preparation. Using a wealth of examples, it compares old and new extraction procedures and explores the many applications of new generation green solvents. Practical, easy-to-follow experiments are used to illustrate the key concepts. This practical guide helps to promote the use of safer, more sustainable solvents in analytical chemistry and beyond for environmental scientists, researchers in pharmaceutical and biotech industries, and students in analytical chemistry. - Covers the basic analytical theory essential for understanding extraction- and microextraction-based separation and preconcentration methods - Explains combination use of new generation solvents with various detection systems, including UV-VIS, ICP-MS, HPLC, LC-MS, GC-MS, and LC-MS/MS - Emphasizes trace chemical component separation, preconcentration and analysis
