Latest Patents

McGahan's most recent patents reflect his commitment to advancing methods for managing toxic substances.

- **Attenuation of Arsenic Leaching from Particulate Material**: This patent outlines a method for treating particulate materials, including soils and sludges that contain arsenic compounds. The process involves treating the materials with a source of iron (III) ions and a source of magnesium (II) ions, effectively stabilizing the materials to prevent arsenic leaching. Iron (III) sulfate serves as a preferred source of iron (III) ions, while magnesium oxide is the suggested source for magnesium (II) ions.

- **Process for Treating Spent Catalyst Including Antimony Halides**: This innovative process involves detoxifying spent catalyst from chlorofluorocarbon production for safe disposal or reprocessing. The spent catalyst contains harmful elements such as antimony and arsenic halides. The treatment process consists of hydrolyzing the catalyst in an aqueous solution of ferric chloride, forming a ferric ion/fluoride ion complex. The method also includes neutralizing the hydrolyzed mass with calcium hydroxide and stripping volatile organics for reuse or disposal, before drying the final product for safe handling.
