Abstract
A method of immobilizing contaminants disposed in an aqueous medium, the method comprising: contacting the aqueous medium with a particulate crystalline nanocomposite for a sufficient contact time to permit adsorption of the contaminants. The particulate crystalline nanocomposite comprises: a hexagonal lanthanum hydroxide (La(OH)3) crystalline phase; a lanthanum oxide (La2O3) crystalline phase; a monoclinic calcium silicate (CaSiO3) crystalline phase; and, a graphitic carbon nitride (g-C3N4) crystalline phase, wherein at least a fraction of the g-C3N4 is in the form of mesoporous nanosheets.
