Commercialization of Nanotechnology for Removal of Heavy Metals in Drinking Water

Density, Refractive Index, and Ultrasound Speed in Mixtures of Active Carbon and Exfoliated Graphite Nanoplatelets Dispersed in N,N-Dimethylformamide at Temperatures from (293.15 to 318.15) K

“…To characterize the type and magnitude of molecular interactions between DMF and xGnP, the density, ultrasound speed, and refractive index of the pure solvent and mixtures of DMF and xGnP were determined. In the present study xGnP dispersed in DMF can be used in environmental and agricultural applications such as composite nanomaterials for sensors (in-field sensing systems to monitor environmental stresses) and sorbents (enabling the delivery of drugs or the removal of contaminants from mixtures of solutions). With respect to water quality, xGnP dispersed in DMF can be used in a variety of applications, such as desalination or the removal of heavy metals.…”

Mechanistic Study of Pb(II) Removal by TiO2 and Effect of PO4

“…All chemicals used were reagent grade and purchased from Fisher or Sigma-Aldrich (United States). Titanium dioxide (TiO 2 ) was obtained from Graver Technologies (United States), which has been used as granular adsorbents in water filters for heavy metals removal (e.g., arsenic, , Pb­(II), and uranium).…”

Applications of Nanotechnology in Fish Health

“…Ligand-centered nano-coating can be utilized to remove heavy metals because it can be restored by handling the bi-functional self-assembling ligand with the nano-coating medium that was used before. This process can be done in the same place where the ligand was used (Farmen 2009). Nanoparticles of metal oxides, such as nanosized FeO, AlO2, MnO, CeO2, MgO and TiO, having increased surface area and affinity for metal adsorption are currently preferred nanotechnology for wastewater treatment.…”

“…For heavy metal removal, ligand-based nanocoating can be used due to its high absorption potential and low cost. Using crystal clear technology for water purification, several metal layers are bonded to one substrate (Farmen 2009). The high reactivity and large surface area of nanomaterials make them ideal for heavy metal removal from water and waste.…”
