Thermodynamics of fluoride adsorption onto mesoporous alumina nanoparticles

Fluoride contamination has been recognized as one of the most serious problems for water quality worldwide. Many methods exist to remove fluoride from water, but adsorption onto nanomaterials can offer several advantages over traditional methods. It is expected that nanomaterials will give better results than traditional sorbents in terms of higher loading capacity and lower residual concentration. Fluoride adsorption by alumina nanoparticles has been investigated in this work using a combined experimental approach which includes potentiometry and isothermal titration calorimetry (ITC).
