Iron-modified hydrotalcite-like materials as highly efficient phosphate sorbents

Mg–Al hydrotalcites as solid base catalysts for alcoholysis of propylene oxide

“…Assuming a 3R stacking of the layers from the positions of the (003), (006), (009), and (110) reflections, the lattice parameters a and c can be calculated [18]. The value of a (2d 110 ) is the average metal-metal distance within the layers while the value of c (3d 003 ) is the total thickness of the brucite-like layer and interlayer distance [19].…”

Adsorptive Removal of Phosphate Ions Using Leached Sea Nodule Residue Generated by the Reduction–Roasting Ammoniacal Leaching Process

“…Extensive research efforts have been devoted during the last decade to studies of the removal of phosphate ions from wastewaters, in order to reduce the anthropogenic input of phosphate into aquatic systems and to control eutrophication. Chemical precipitation, adsorption/ion-exchange and biological methods are some of the common approaches that have been successfully employed for the removal of excess phosphate ions from contaminated water (Jenkins and Hermanowicz 1991;Oguz et al 2003;Wu et al 2007;Chen et al 2006;Srivastava and Srivastava 2005;Triantaflyllidis et al 2010;Blaney et al 2007). However, chemical precipitation and biological methods are often not capable of removing phosphate ions to levels that can satisfy many stringent effluent standards.…”

“…As a result, the adsorptive removal of phosphate ions from aqueous solutions has gained the increasing attention of many researchers across the globe. A wide variety of adsorbents, both natural and synthetic, have been used to date and the search for further improvement is still continuing (Triantaflyllidis et al 2010;Özacar 2003;Zhu and Zhu 2007;Karageorgiou et al 2007;Nowack and Stone 2006;Mustafa et al 2006;Ou et al 2007; Kuzawa et al 2006;Karaca et al 2006). In recent years, efforts have been made to use low-cost and easily available materials such as mining and industrial wastes in wastewater treatment as a means of utilizing these wastes.…”

Preparation of Adsorbent with High Removal Ability for Phosphate Ion from Blast Furnace Slag using Alkali Fusion

“…[26,27] . These LDH can remove phosphate ion by ion exchange between anion species in LDH and phosphate ion in the solution, and LDH has different affinity for phosphate, depending on anion species in LDH guest layer.…”
