Adsorption of arsenate on Cu/Mg/Fe/La layered double hydroxide from aqueous solutions

Mechanism of boron uptake by hydrocalumite calcined at different temperatures

“…The pseudo first-order and pseudo second-order kinetic models have been explored to express the sorption kinetics. The pseudo first-order kinetic model and pseudo second-order kinetic model are expressed as [29]:…”

Simultaneous removal of arsenate and antimonate in simulated and practical water samples by adsorption onto Zn/Fe layered double hydroxide

“…Based on our previous researches on arsenic adsorption with several novel materials [27][28][29], the objective of this work is to develop an efficient functional material for the adsorption of coexistent As(V) and Sb(V) in water, and investigate the possibility of simultaneous removal of both arsenate and antimonate for practical polluted water samples. In this study, a ferric-based layered double hydroxide material (Zn-Fe-LDH) has been synthesized and used to study the adsorption performance for arsenate and antimonate in aqueous solutions.…”

The photocatalytic property for water splitting and the structural stability of CuMgM layered double hydroxides (M=Al, Cr, Fe, Ce)

“…The wide choice of metal cations and interlayer anions give rise to a series of layered functional materials. They are widely used in the fields of anion exchange, adsorption (Guo et al, 2012;Shimamura et al, 2013;Tang et al, 2015), drug delivery reagents (Oliver, 2009;Zhao et al, 2012a,b), electrochemistry Tonelli et al, 2013), functional polymers (Zhou et al, 2011;Miranda et al, 2013), catalysts (Kantam et al, 2012;Lopez-Martinez and Shannon, 2012;Chubar et al, 2013;Mendoza-Damian et al, 2013), and so on. Particularly, when the Mg or Al element in the octahedral structure was replaced by other metal elements such as Zn, Cu and Ti, it would narrow the energy gap, enable the electrons being excited easily by visible light to create the electronhole pair and therefore increase the photo-catalysis activity (Wang and O'Hare, 2012;Xia et al, 2014).…”
