“…Due to its lower carbon content (43.19%) and greater iron concentration (8.01%) compared to MPAC-500 which had a higher carbon content (71.75%) and a lower iron level (1.49%), MPAC-600 showed superior adsorption effectiveness. Furthermore, Swain et al (2019) employed zirconium-impregnated carbon-rich PPW, obtained using zirconium oxychloride (ZrOCl 2 ·8H 2 O) solution and ground PPW, as an engineered biochar substance for the removal of fluoride from aqueous solutions. Remarkably, this material successfully absorbed 95% to 98% of the fluoride at a high adsorption rate.…”

“…On the other hand, D F reached an equilibrium state from pH 7 to pH 10. It may be because the number of positively charged sites on the adsorbent surface decreases while increasing the solution pH [35]. In an alkaline system, the surface of ETSSs was accumulated with negative charge OHions, causing repulsion between the negatively charged surface and fluoride.…”

“…Under this condition, the corresponding adsorption capacity was 5.02 mg/g, which was 2.37 mg/g higher than that in the absence of F − . it was mainly due to that on the one hand, Pb 2+ could coordinate with the neighboring phenolic hydroxyl groups on TF-Zr, on the other hand, the electrostatic adsorption of Pb 2+ could possibly happen on the TF-Zr surface after F − adsorption (Swain et al 2019). It was also found that the adsorption e ciency of TF-Zr on F − increased and then decreased with the increase of F − concentration, which was attributed to the facts that when the amounts of TF-Zr adsorbent were constant, the active sites were limited.…”
