The U.S. Department of Energy’s National Energy Technology Laboratory (NETL) has developed a system and method for combining polyamines, which immobilizes the dye-absorbing amine sites within low cost, porous silica particles. The innovation has the potential to remove organic-based colorants and pollutants from different water sources. This invention is available for licensing and/or further collaborative research from NETL
This innovation can covalently immobilize dye-absorbing amine sites with low cost, porous silica particles. The sorbents have the potential to remove other organic-based colorants and pollutants from different water sources.
Anticipated uses of the invention primarily include any flowing or stagnant aqueous system with dye materials including drinking water, ponds, rivers, lakes, seawater, and groundwater. Some key sources for the dye can be from textile waste water streams, food processing waste water streams, and coffee bean waste waters. Alternative uses of the invention includes the adsorption of toxic organic materials that bear structural similarity to the dye molecules.
