Extraction Techniques for Environmental Analysis

Explore the analytical approach to extraction techniques

In Extraction Techniques for Environmental Analysis, accomplished environmental scientist and researcher John R. Dean delivers a comprehensive discussion of the extraction techniques used for organic compounds relevant to environmental analysis. In the book, extraction techniques for aqueous, air, and solid environmental matrices are explored and case studies that highlight those techniques are included.

Readers will find in-depth treatments of specific extraction techniques suitable for adoption in their own laboratories, as well as reviews of relevant analytical techniques used for the analysis of organic compound extracts (with a focus on chromatographic separation and detection).

Extraction Techniques for Environmental Analysis also includes a chapter that extensively covers the requirements for an analytical laboratory, including health and safety standards, as well as:
_ A thorough introduction to pre-sampling, as well as the extraction of aqueous samples, including the classical approach for aqueous extraction and solid phase extraction
_ Comprehensive explorations of the extraction of gaseous samples, including air sampling
_ Practical discussions of the extraction of solid samples, including pressurized fluid extraction and microwave-assisted extraction
_ In-depth examinations of post-extraction procedures, including pre-concentration using solvent evaporation

Extraction Techniques for Environmental Analysis is a must-read resource for undergraduate students of applied chemistry, as well as postgraduates taking analytical chemistry courses or courses in related disciplines, like forensic or environmental science.
