Effective and fast adsorptive removal of fluoride on CaAl₂O₄:Ba nanoparticles: isotherm, kinetics and reusability studies

Investigation of kinetics and adsorption isotherm for fluoride removal from aqueous solutions using mesoporous cerium–aluminum binary oxide nanomaterials

“… 66,67 The pore volume and average pore diameter were determined to be 0.141 cc per g and 3.673 nm, respectively, indicating the surface to be mesoporous. The pore diameter of an adsorbent as observed is greater than the average pore diameter of fluoride ions 68,69 (0.133 nm), suggesting F − to readily enter the adsorbent's pores. A graph is plotted between P / P 0 and 1/[ W ( P 0 / P ) − 1], which shows linear variation, suggesting that the adsorbent is highly porous.…”
