Sorption characteristics and mechanisms of oxyanions and oxyhalides having different molecular properties on Mg/Al layered double hydroxide nanoparticles

Synthesis, characterization, and application of Fe-CNTs nanocomposite for BrO3− remediation from water samples

“…3) as revealed from a plateau region. The obtained equilibration time was extremely fast compared to previously reported studies (20, 10, and 4 h as an equilibration time) [21,24,39]. The adsorption capacity at equilibrium (q e ) increased from 2.9 to 16.35 mg/g when initial BrO 3 À was increased from 1 to 5 mg/L, respectively.…”

“…Iron based nanomaterials are a promising alternative for industrial scale wastewater treatment applications as they are cost effective, have high adsorption capacity, easy separation and enhanced stability. Nano-sized adsorbents such as Mg/Al layered double hydroxide [24] and nano-crystalline akaganeite (iron oxide) coated quartz sand [25] have been reported for the removal of BrO 3 À from aqueous solutions. The fast BrO 3 À adsorption kinetics was observed on nano-crystalline akaganeite coated quartz sand than on Mg/Al Journal of Industrial and Engineering Chemistry 26 (2015) 218-225 layered double hydroxide nanosized adsorbent, attaining equilibrium in 10 min.…”

Equilibrium and kinetics studies on As(V) and Sb(V) removal by Fe2+-doped Mg–Al layered double hydroxides

“…LDHs have been investigated for water preservation and purification. For example, LDHs can take up oxometalates such as arsenite, arsenate, chromate, and selenite, or oxyhalides such as bromate, chlorate, and iodate from aqueous solutions (Goh et al, 2008;Mandal et al, 2009;Goh et al, 2010;Goh and Lim, 2010;Yuan et al, 2013;Theiss et al, 2014). Some studies also examined the treatment of antimonate using LDHs (Kameda et al, 2011(Kameda et al, , 2012a.…”

Sorption properties of boron on Mg–Al bimetallic oxides calcined at different temperatures

“…Hydrotalcite adopts a layered, double-hydroxide structure and has a general chemical formula [ , dodecylbenzylsulfonate, 2,4,6-trinitrophenol [18][19][20][21][22][23][24].…”
