An Efficient, Green Process for Cyanide Decontamination in Water

Description:

An Efficient, Green Process for Cyanide Decontamination in Water

Princeton Docket # 14-2955

This innovation is an improvement to a previously patent pending process for the catalytic generation of chlorine dioxide, Princeton docket # 11-2630/2714, US Patent Publication 2013-0209573, “An Efficient, Catalytic and Scalable Method to Produce Chlorine Dioxide” which refers to a manganese catalyzed process for the production of chlorine dioxide. Continuing their research with manganese catalysts, chemists at Princeton University have identified a novel improvement for generating chlorine dioxide while at the same time achieving rapid depletion of cyanide ions and hydrogen cyanide.

There is a clear need to decontaminate water that contains cyanide ions or hydrogen cyanide. This innovation is an improvement to our manganese-catalyzed process invention for the production of chlorine dioxide and is able to rapidly, efficiently and catalytically remove cyanide ion and hydrogen cyanide from water. This improvement further adds to the Green Chemistry aspect of this catalysis and, at scale, might afford the user a carbon capture credit as well.

Applications:

· Decontamination of cyanide ion and hydrogen cyanide from water

· Use in mining operation and other industrial operations

Advantages:

· Efficient and scalable

· Potential for carbon capture credit

· Green chemistry

· Applicable under mild pH conditions

Principal Investigator and Inventor

Professor John T Groves, Professor of Chemistry

Professor Groves major thrust of research is at the interface of organic, inorganic, and biological chemistry. Many biochemical transformations as well as important synthetic and industrial processes are catalyzed by metals. Current efforts focus on the design of new, biomimetic catalysts and the molecular mechanisms of these processes, the design and assembly of large scale membrane-protein-small molecule constructs, studies of host-pathogen interactions related to iron acquisition by small molecule siderophores and molecular probes of the role of peroxynitrite in biological systems. Professor Groves is the recipient of many accolades, including most recently his election to the National Academy of Sciences in 2012.

Intellectual Property (and Development or Technology) Status

Patent protection is pending. Princeton is seeking industrial collaborators for the further development and commercialization of this technology.
