Abstract
Zero-valent iron and bimetallic nanoparticles are very effective for the dechlorination of organics (e.g., trichloroethylene, TCE), but are prone to oxidation when exposed to air. Incorporation of the nanoparticles in a membrane phase may minimize oxidation and simplify the engineering of nanotechnology-based systems for water treatment. The polymer phase is also a strong absorbent for the organic, and retains the organic in the solid phase, even if the dechlorination rate is low. Nanoparticles composed of iron and combinations with nickel and palladium are synthesized in solution using common microemulsion techniques. The nanoparticles are continuously kept in organic solvent to inhibit oxidation, and are transferred to the polymer (cellulose acetate, CA) phase as slurry. Flat sheet membranes are made from this polymer dispersion using conventional and scalable phase inversion techniques.
