Swellable organosilica (Osorb�) is a sol-gel derived material that absorbs up to 8 times of its dry weight in neat organics and has high affinity for dissolved organic species. The absorption/swelling process is in part mechanically driven and is reversible. Osorb� was successfully used for partition of range of species from aqueous solutions, such as produced waters, run off landfill recovery, and catalysis. This presentation will focus on the fundamental aspects of how Osorb removes organic from aqueous phases.
