Abstract: A method of selectively recovering a lipophilic target substance. An insoluble adsorbent is exposed to a solution of the target substance in a lipophilic solvent. Adsorption of the adsorbent with the target substance is facilitated by addition of hydrophilic solvent, which is less hydrophobic than the lipophilic solvent, to the solution during or after exposure of the solution to the insoluble adsorbent, lowering the temperature of the solution or evaporating a portion of the lipophilic solvent. The adsorbent Is isolated from the solution. For desorbing and recovering the target substance, a hydrophobic dissociation fluid may be combined with the adsorbent, a temperature of the adsorbent may be increased or a portion of the hydrophilic solvent may be evaporated. A solution may be exposed to one or more adsorbents for recovering additional lipophilic target substances, recovering hydrophilic target substances or removing unwanted substances.
