Summary
Underlying chemical properties that govern extraction procedures such as vapor pressure, solubility, molecular weight, hydrophobicity, and acid dissociation are described. Techniques for the extraction of semivolatile organics from liquids are discussed. These include liquid–liquid extraction (LLE), solid-phase extraction (SPE), solid-phase microextraction (SPME), and stir bar sorptive extraction (SBSE). Method fundamentals for these procedures are categorized according to equilibrium/non-equilibrium and exhaustive/non-exhaustive extractions. Methodology, procedures, and recent advances in techniques are presented.
