— A new sorbent (Al-D) for the removal of fluoride ions is prepared by modifying diatomite with aluminum ions. The sorbent is studied using X-ray diffraction, thermogravimetry, X-ray photoelectron spectroscopy, and adsorption structure analysis; its ability to remove fluoride ions from model aqueous solutions is measured under static conditions. The diatomite, which is modified by heterogeneous hydrolysis...
