Phosphate removal from water using lithium intercalated gibbsite

Preparation, characterization of wheat residue based anion exchangers and its utilization for the phosphate removal from aqueous solution

“…The protonation of WR-AE surface is caused by the high concentration of H + when the pH is lower than 3.0, which makes the species of phosphate in aqueous solution exists in the form of H 3 PO 4 and H 2 PO 4 − (Wang & Cheng, 2007). As the pH increases increase gradually with the significant decrease of protonation.…”

Adsorption characteristics of used brick for phosphorus removal from phosphate solution

“…Meanwhile, some other wastes, such as eggshell [14], giant reed [15], skin split [16], coir pith [5], sugarcane bagasse fibers [17], and pine sawdust [18][19][20], have been modified to adsorb phosphorus. In addition, some new approaches, such as lithium intercalated gibbsite [21], magnetic ion-exchange resin [22], chitosan hydrogel beads after the removal of copper (Ⅱ) [23], activated carbon loaded with Fe(III) oxide [24], zirconium(IV)-loaded fibrous [25], have also been developed to remove phosphorus.…”

Phosphate adsorption from aqueous solutions by disused adsorbents: Chitosan hydrogel beads after the removal of copper(II)

“…A variety of adsorbents have been developed such as cationic metal-EDA complexes anchored inside mesoporous silica MCM-41 supports [5], the chitosan-g-poly(acrylic acid)/vermiculite ionic hybrid [11], slag [12], red mud [13], palygorskite [14], iron-based components [15], zirconium [16], coal fly ash [17], crab shells [18], lithium [19], and MgMn-layered double hydroxides [20]. Among these adsorbents, metal ions play an important role in the adsorption of phosphate because they are facile in binding with phosphate.…”
