Uptake properties of phosphate on a novel Zr–modified MgFe–LDH(CO3)

Engineered nanomaterials for water treatment and remediation: Costs, benefits, and applicability

“…Several studies have investigated the effectiveness of various Me/MeO ENMs for the removal of phosphate from waters. These include Mn-doped Al-based bimetal oxides [465], ZrO 2 -coated graphite oxide [466], and Zr-modified MgFe layered double hydroxide carbonates in seawater [467].…”

Hydrothermal synthesis of Mg–Al layered double hydroxides (LDHs) from natural brucite and Al(OH)3

“…, SO 4 2À [2,3]. Hydrotalcite-like compounds, also called layered double hydroxides (LDHs), have received considerable interest in recent years owing to their layered structure and high anion-exchange capacity [4], which makes them potential materials for technical applications in many technological fields [5].…”

“…Hydrotalcite is a kind of hydroxycarbonate of magnesium and aluminum with the layered structure, belonging to the class of anionic clays, with the formula of [Mg 6 Al 2 (OH) 16 The value x has a range between 0.17 and 0.33, while A nÀ is an interlayer anion with a negative charge n, and m is the number of water molecules [1,2]. Many anions or anionic complexes, both organic and inorganic, can be incorporated into the hydrotalcite structure.…”

Treatment of NO and NO2with a Mg−Al oxide slurry

“…[5][6][7][8][9][10][11][12][13][14][15][16][17] Equation 4 indicates that the rehydration and subsequent combination of Mg-Al oxides with anions in solution are accompanied by the release of OH − . Thus, Mg−Al oxides also have the capacity to neutralize acids such as H 2 SO 4 , HCl, and HNO 3 .…”
