1. 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 comprising:
a calcium hydrogen phosphate (CaHPO4) crystalline phase;
a calcium silicate hydroxide (Ca6Si6O17(OH)2) crystalline phase;
a silicon dioxide (SiO2) crystalline phase; and,
a graphitic carbon nitride (g-C3N4) crystalline phase,
wherein at least a fraction of the graphitic-C3N4 is in the form of mesoporous nanosheets.
