Membrane extraction techniques in environmental analysis

Jönsson, Jan Åke LU (2005) In Ecological Chemistry and Engineering S-Chemia i Inzynieria Ekologiczna S 12(5-6). p.519-539
Abstract
Membrane assisted extraction facilitates the integration of classical liquid-liquid extraction (LLE) chemistry to automated instrumental analysis. Various shortcomings of classical LLE are overcome by the membrane separation of sample (donor) and extract (acceptor): 1) reduced solvent usage, 2) higher enrichment factors, 3) no solvent evaporation and 4) no formation of emulsions. Membrane extractions provide a high degree of clean-up, permitting automated analysis of environmental and biological samples with no or very small consumption of organic solvents. This review gives a short overview of membrane extraction in environmental analytical chemistry. The principles of the equilibrium extraction approach will be described and examples... (More)

Membrane extractions provide a high degree of clean-up, permitting automated analysis of environmental and biological samples with no or very small consumption of organic solvents. This review gives a short overview of membrane extraction in environmental analytical chemistry. The principles of the equilibrium extraction approach will be described and examples involving applications to environmental samples will be presented. Keywords: Membrane extraction, Supported liquid membrane extraction, SLM, MMLLE, Liquid Phase Microextraction, Selectivity, Enrichment, Equilibrium extraction (Less)
