REMOVAL OF HEAVY METALS FROM AQUEOUS SOLUTIONS USING METAL-DOPED TITANIUM DIOXIDE NANOPARTICLES |
| 摘要 |
The removal of heavy metals from aqueous solutions using metal-doped titanium dioxide nanoparticles is a method that comprises contacting the aqueous solution with metal-doped titanium dioxide nanoparticles. The three transition metals tungsten, vanadium and iron were selected for doping of titanium dioxide. Removal of the toxic heavy metals Pb(II), Zn(II) and Cd(II) was studied intensively by using metal-doped titanium dioxide to measure the isotherms and kinetics. The isotherms studies showed that the highest removal percentage of Pb(II) was achieved by W-doped titanium dioxide, while Fe-doped titanium dioxide and V-doped titanium dioxide performed better for removal of Zn(II) and Cd(II), respectively. |
