Abstract
A membrane-based inverted liquid-liquid extraction method for extracting an analyte from an unsupported aqueous liquid sample includes sealing the unsupported aqueous liquid sample in a porous membrane bag, immersing the porous membrane bag in an organic solvent, and extracting the analyte from the unsupported aqueous liquid sample to produce an extract within the organic solvent. The unsupported aqueous liquid sample is immiscible with the organic solvent. The porous membrane bag does not contain a solid sorbent.
