Abstract
A method of immobilizing contaminants disposed in an aqueous medium, the method including contacting the aqueous medium with a CaHPO4/Ca6Si6O17(OH)2/g-C3N4 particulate crystalline nanocomposite for a sufficient contact time to permit adsorption of the contaminants. The particulate crystalline nanocomposite includes: 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 g-C3N4 is in the form of mesoporous nanosheets.
