On the conversion of bauxite ores to highly activated alumina media for water remediation... This acid-treated, thermally activated bauxite (ATAB) exhibits a high surface area of 401 ± 6 m2 g−1, a 40-fold increase relative to its parent ore, and a 2× increase relative to the state-of-the-art fluoride...
Addressing technical barriers for reliable, safe removal of fluoride from drinking water using minimally processed bauxite ores... We evaluate competition from co-occurring ions, adsorption reversibility, and potability of the product water with regards to leaching of undesirable ions during treatment with various adsorbent materials including raw and thermally activated bauxite, and synthetic gibbsite (a simple model system)....
