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.

Liquid-liquid extraction with particulate polymeric adsorbent

In the membrane filtration of a liquid cell culture medium, superior flux rates and product recovery are obtained when a first charged particulate material and optionally a second charged particulate material bearing a charge opposite that of the first material are sequentially added to the medium prior to filtration.
