The present invention relates to a method of separating a target from a liquid, which includes providing a polymer in an aqueous liquid, which polymer comprises at least one hydrophobic portion; contacting the polymer-containing liquid with the liquid comprising the target; applying a stimulus to the resulting mixture; and maintaining it until a reversible phase separation is obtained. One phase is polymer-rich and contains target(s) and another phase is polymer-poor. By either maintaining the stimulus, or applying a different stimulus and maintaining it, the polymer-rich phase is transformed into a substantially solid phase.
