Patent abstract
Nanolayered layered silicate materials of octahedrally arranged units with divalent metal ions at centers of the units covalently linked above and below to tetrahedrally arranged oxygen and hydroxyl units with silicon atoms. The silicate materials contain silanol groups which are reactive to form derivative compositions useful for water purification to remove heavy meal cations.
