The concentration of Fe2+ or Mn2+ ions in the aqueous mixture is in the range of about 0.0001% to about 0.001%. The enhanced formulations can be delivered, for example, as a foam, spray, liquid, fog, mist, or aerosol for neutralization of chemical compounds, and for killing certain biological compounds or agents and mold spores, on contaminated surfaces and materials.Type: GrantFiled: January 27, 2006Date of Patent: February 16, 2010Assignee: Sandia CorporationInventors: Mark D.

Publication number: 20100036188Abstract: A molecularly imprinted polymer and production process therefor and a process for selective treatment of poorly degradable and/or toxic compounds in liquids using the molecularly imprinted polymers. Such polymers and processes are required for selective removal and/or degradation of biological, poorly degradable pollutants or toxic compounds, for example from wastewaters. Consequently, a molecularly imprinted polymer suitable for the selective treatment of at least one poorly degradable and/or toxic compound is provided having a polymeric network which is made up of monomers and has cavities of predetermined size, wherein the cavities are arranged at predetermined spacings and have specific binding sites and/or patterns for the poorly degradable and/or toxic compounds.Type: ApplicationFiled: February 20, 2007Publication date: February 11, 2010Applicant: KIST-EUROPE FORSCHUNGSGESELLSCHAFT MBHInventors: Ute Steinfeld, Barbara Palm
