Sorption of perfluorooctane sulfonate and perfluorooctanoate on activated carbons and resin: Kinetic and isotherm study. (2009, positive): “The determination of the point of zero charge (pHpzc) for the activated carbons was carried out as follows (Faria et al., 2004): 50 mL of 0.01 M NaCl solution was placed into each conical flask, and the solution pH was adjusted from 2 to 12 with 0.01 M HCl or NaOH solution.”
Activated carbons treated with sulphuric acid: catalysts for catalytic wet peroxide oxidation (2010, background): “The influence of PZC of activated carbons in the adsorption of anionic and cationic dyes is well documented in the literature [27].”
Biosorption of Heavy Metal Ions from Aqueous Solutions Using a Biomaterial (2009, result): “This is similar to the findings of others, where the interaction between oxygen-free Lewis basic sites and the free electrons of the anions, as well as the electrostatic interactions between the anions and the protonated sites of the adsorbent are the main adsorption mechanism [20, 21, 22].”
Application of biochar for the removal of pollutants from aqueous solutions. (2015, positive): “As an adsorbent, biochar has porous structure similar to activated carbon, which is the most commonly employed and efficient sorbent for the removal of diverse pollutants from water throughout the world (Faria et al., 2004; Nakagawa et al., 2004; Chen et al., 2007).”
Removal of heavy metal from industrial wastewater using chitosan coated oil palm shell charcoal (2005, background): “At higher pH, the presence of oxygencontaining functional groups, makes the adsorbent surface negatively charged and hence there is repulsive electrostatic interaction between the adsorbent and the anions (Radovic et al. 1997; Faria et al. 2004).”
Adsorptive removal of antibiotics from water and wastewater: Progress and challenges. (2015, background): “As an adsorbent, BC has the porous structure almost similar to AC and thus can act as an efficient sorbent for the removal of diverse pollutants from water and wastewater (Chen et al., 2007; Faria et al., 2004; Nakagawa et al., 2004).”
