Kinetics of phosphate adsorption by Ca/Cr layered double hydroxide (LDH) in a batch reactor was investigated this study. The kinetic experiments indicated that the sorption from synthetic feed solution synthesised LDH very fast, with over 98% removal being achieved within 5 min contact. Kinetic modeling process to different models (pseudo first order, pseudo second Elovich and intraparticle dif...

The synthesis and applications of composites based on layered double hydroxides (LDHs) nanocarbons have recently seen great development. On the one hand, LDHs are versatile 2D compounds that present a plethora applications, from medicine to energy conversion, environmental remediation, heterogeneous catalysis. other, unique physical chemical properties owing their low-dimensional structure sp2 ...

A series of novel layered double hydroxides (Mg-Fe-Ti-LDHs) containing Mg2+, Fe3+ and Ti4+ were prepared. The adsorption performance Mg-Fe-Ti-LDHs on vanadate in aqueous solution was investigated the effects various factors process examined, including initial concentration, adsorbent dosage, contact time, pH coexisting ions. preliminary discussion mechanism also presented. Results show that eff...

Aerogels of layered double hydroxides were prepared by a simple and eco-friendly method involving a quick coprecipitation followed by supercritical CO(2) drying. Such aerogels display high surface areas and enhanced adsorption behavior.
