The extraction or purification of biomaterials and other products by liquid-liquid extraction in an aqueous system is enhanced by introducing a particulate polymeric adsorbent into the extraction system and agitating the system, whereupon the adsorbent reversibly binds the product or material to be separated from the product, to form a complex, and the complex preferentially partitions into one of the liquid phases. The complex is then separated, and the product recovered from the complex or the remaining liquid. Ion exchange resins comprising beads or ground particles, of 0.01-10 micrometer average diameter, are representative adsorbents. |
