Nanomaterials usage as adsorbents for the pollutants removal from wastewater; a review

Corrosion Protection of Carbon Steel Using Expired Drug in Acidic Medium

“…In simpler words, though is important to note that the corrosion of the Cs in the Chlorine ions containing solutions will still take place, the boosted energy barrier will hinder the process when the inhibitors are present. As well, the intensity of corrosion is enhanced by increment in temperature which affects the effectiveness of inhibitors [22]. An increase in inhibitor concentration results in an increase in saturation of the electron density at the adsorption site of the inhibitor molecule, and hence, the inhibition becomes much more effective.…”

Comparison of Adsorptive Removal of Fluoride from Water by Different Adsorbents under Laboratory and Real Conditions

“…NMF combines the advantages of a TiO 2 coating, which infers a high affinity to fluoride, with the nano-size of the particles that improves the surface area, reactivity, isolation properties and selectivity for pollutants [35]. Furthermore, with respect to most of the commercial adsorbents such as those tested in the present study, NMF offers a further and important advantage: they can be easily separated from the treated liquid solution by using simple magnets [36].…”

Porous carbons prepared from a novel hard wood composite waste for effective adsorption of Pb(ii) and Cd(ii) ions

“…7,8 Accordingly, different adsorbents have been developed for removal of heavy metals such as porous carbon-based materials, including activated carbon/biochar, carbon nanotubes and graphenes analogues, which have been widely studied due to their wide distribution, large specific surface area, pore structure and low cost. 9–14 Activated carbon, which can be obtained by carbonization and activation of very wide carbon rich precursors, is considered as a promising heavy metals adsorbent due to its relatively high mechanical strength. 15…”

“…7,8 Accordingly, different adsorbents have been developed for removal of heavy metals such as porous carbon-based materials, including activated carbon/biochar, carbon nanotubes and graphenes analogues, which have been widely studied due to their wide distribution, large specic surface area, pore structure and low cost. [9][10][11][12][13][14] Activated carbon, which can be obtained by carbonization and activation of very wide carbon rich precursors, is considered as a promising heavy metals adsorbent due to its relatively high mechanical strength. 15 In recent years, the preparation of activated porous carbons from biomass feedstock through hydrothermal carbonization followed by chemical activation has received great attention 16,17 and is considered as an alternative to thermochemical synthesis method to produce solid hydrochar materials with high concentrations of oxygenated functional groups at moderate temperatures (ca.…”
