Abstract
A method of removing a contaminant from water may include contacting contaminated water, including a heavy metal and/or an organic pollutant, with a nanocomposite including graphitic C3N4, V2O5, and MgAl2O4 in a mass relationship to each other in a range of from 5 to 15:2 to 7:75 to 95, thereby adsorbing the heavy metal and/or the organic pollutant onto the nanocomposite, as an adsorbed material. The method may further include removing the adsorbed material from the contaminated water, thereby reducing a concentration of the heavy metal in the contaminated water by at least 2 percent by weight (wt. %), the heavy metal includes Cd, Cr, Cu, Fe, Pb, Ni, Ag, Zn, and/or U, and the organic pollutant includes a dye.
Claims18
A method of removing a contaminant from water, the method comprising:
- contacting contaminated water, comprising a heavy metal and optionally an organic pollutant, with a nanocomposite comprising graphitic C3N4, V2O5, and MgAl2O4 in a mass relationship to each other in a range of from 5 to 15:2 to 7:75 to 95, thereby adsorbing at least some of the heavy metal and the organic pollutant, if present, onto the nanocomposite, as adsorbed material, and form a nanocomposite adsorption product;
- and
- removing the adsorbed material from the contaminated water, thereby reducing a concentration of the heavy metal in the contaminated water by at least 2 wt. %,
- wherein the heavy metal comprises ions of Cd, Cr, Cu, Fe, Pb, Ni, Ag, Zn, and/or U, and
- wherein the organic pollutant comprises a dye.
