DESCRIPTION:As the population of the world continues to grow\, the diminish
 ing availability of clean water is becoming a serious global problem. Acco
 rdingly\, water recycling is becoming increasingly common\, but this often
  results in serious contamination with recalcitrant organic pollutants (e.
 g. agri-chemicals\, active pharmaceutical ingredients\, endocrine disrupto
 rs\, etc.). Problems with current water purification methods include the f
 ormation of potentially toxic organochlorines\, generation of large volume
 s of waste\, high energy consumption and expense. There is a need to find 
 a highly effective\, inexpensive and simple method of water purification t
 hat would be appropriate for widespread adoption. We have attempted to add
 ress this problem by creating a smart catalytic film that oxidatively dest
 roys organic pollutants as the contaminated water simply runs over its sur
 face. The specially designed film anchors an oxidation catalyst\, concentr
 ates the dilute aqueous organic pollutants bringing them in close contact 
 with the catalyst\, and keeps the hydrogen peroxide oxidant solution separ
 ate from the water to be purified while allowing the hydrogen peroxide to 
 slowly perfuse through the film in a controlled way to activate the cataly
 st sites.  In this way the catalytic film oxidatively destroys organic pol
 lutants without the water needing to be dosed (or contaminated) with oxida
 nt\, catalyst or other reagent. The film has been shown to oxidatively des
 troy both surrogate pollutants as well as “real world” pollutants such as 
 triclosan\, EE2\, and bisphenol A. Details of the design\, construction an
 d performance of the smart catalytic film\, as well as its operation in se
 veral different configurations\, will be presented.\n
