Perstraction: A Membrane-Assisted Liquid–Liquid Extraction of PFOA from Water

This study represents a first time that perstraction was assessed as process to remove perfluorooctanoic acid (PFOA) from water. In the process, PFOA permeates through membrane water solvent. The used in this polydimethylsiloxane (PDMS). experimental approach included following: (1) measurement of partition coefficients for between and selected solvents; (2) determination solubility diffusivity solvents PDMS; (3) uptake (4) effects particles imbedded PDMS on solvent absorption; (5) demonstration preferentially partitioned alcohols over addition, ZnO CuO significantly enhanced rate at which absorbed deionized due ionic interactions. into hexanol demonstrated. However, not successful removing tap While application is limited, idea demonstrated information contained within manuscript new.
