摘要： A method for selectively extracted species from an aqueous solution which comprises contacting the aqueous solution with a membrane capable of selectively transporting species from a liquid to another, the membrane comprising a porous polymer support having an average surface pore size less than 100 nm, coated with a continuous layer of a fluorinated polymer obtained by plasma energized chemical vapor deposition (PECVD) using a plasma containing at least one fluorinated compound.
