Abstract
Disclosed herein are compositions and methods for sequestering heavy metal atoms, including hazardous atoms such as lead and radiocesium, from contaminated areas. The heavy metal atoms may be removed by contacting the contaminated area with a potassium-depleted muscovite-enriched composition. The compositions may also be incorporated into building materials to create structures to safely house nuclear reactors and other devices which may accidentally release heavy metal atoms.
Claims22
A method for sequestering heavy metal atoms from a contaminated area, comprising contacting the contaminated area with a muscovite-enriched mineral composition, wherein the muscovite is potassium-depleted.
(canceled)
A building material comprising a muscovite-enriched mineral composition, wherein the muscovite is potassium-depleted, and contains no more than 10% by mass of potassium relative to the total mass of the muscovite.
