Various materials have been used to adsorb CR through adsorption process: NiO/graphene nano sheets; MWCNTs/LDHs; NiMgAl-LDOs; α-Fe2O3 nanorods; Bentonite/Zeolite-NaP; Ca-Al LDH; Al(OH)3/CuMnAl-LDH nanocomposite; NiFeLDH nanosheet/carbon fiber nanocomposite. Among of these, LDH type materials are of particular interest due to some advantageous properties. In the present study, MgAl-LDH was employed as an adsorbent for CR adsorption. The data were processed using Pseudo first order and Pseudo second order models. The kinetics of CR adsorption onto material was described with the Pseudo-second order model, with a maximum adsorption capacity of 40.44 mg/g. |
