The present invention provides in one aspect, a novel method for recovering an organic solute from a predominantly aqueous solution. In one embodiment, the solution is contacted with a dry, non-conditioned sorbent medium held by a supporting structure, whereby the solute is absorbed onto the matrix by hydrophobic interactions. A solvent is then passed through the medium, thereby desorbing the solute. Finally, the solute is collected. A further aspect of the invention provides water-wettable sorbent materials for use in solid phase extractions. Embodiments of polymer-based and silica-based sorbent materials are disclosed.

[ It is claimed:] [1.] A method for recovering an organic solute from a predominantly aqueous solution using a dry, non-conditioned sorbent medium held by a supporting structure, comprising:contacting the solution with the dry, non-conditioned sorbent medium, wherein the medium is a blend of (i) a polymethacrylate resin and (ii) a polystyrene resin, whereby the solute is absorbed onto the matrix;flowing a solvent or solvent mixture through the medium, thereby desorbing the solute; andcollecting the solute from the medium.
