Abstract
A method of immobilizing contaminants disposed in an aqueous medium, the method including contacting the aqueous medium with a particulate crystalline nanocomposite for a sufficient contact time to permit adsorption of the contaminants. The particulate crystalline nanocomposite includes: a monoclinic Bi2O3 crystalline phase; a CaSiO3 crystalline phase, and, a graphitic-C3N4 crystalline phase, wherein at least a fraction of the graphitic-C3N4 is in the form of mesoporous nanosheets.
