Shevade, S. AND R G. Ford*. UTILITY OF ZEOLITES IN HAZARDOUS METAL REMOVAL FROM WATER. Presented at 226th ACS Nat'l. Mtg, New York, NY, September 07 - 11, 2003.

Impact/Purpose:

To inform the public.

Description:

Zeolites are well known for their ion exchange, adsorption and acid catalysis properties. Different inorganic pollutants have been removed from water at room temperature by using synthetic zeolites. Zeolite Faujasite Y has been used to remove inorganic pollutants including arsenic, cadmium and lead from water in continuous flow reactions below EPA's maximum contamination limits. Simultaneous behavior of zeolite Y as an anion exchanger and cation exchanger has been observed. Mixtures of these zeolites have been tested for complex matrix of the water pollutants. The zeolites showed a very good pollutant removal capacity with contact time less than 1 min. The pollutant removal capacity of the zeolites over a wide pH range may be useful in determining the next generation wastewater treatment. The apparent removal mechanisms for the various contaminants include cation and anion / ligand exchange for various inorganic contaminants.
