Modeling of Solid-Fluid non-catalytic Processes for Nickel Ion Removal

Abstract:

The aim of this study is modeling of the process of Ni(II) removal onto new materials synthesized by a facile coprecipitation method. The literature presents different surfactants intercalated on MgAl-LDH with applicability for nickel ions removal, but the researches on the use of this material ‘’as cast’’ as adsorbent for Ni(II) ions are limited, it is reason to develop this study. The morphology, chemical composition, and the basic structure of the new material were analyzed by SEM, EDAX, BET, XRD and FT-IR. The kinetic modeling was performed using the pseudo-first-order, four-type linear pseudo-second-order, and intraparticle diffusion. The experimental data demonstrated that the adsorption process is very fast in the first 20 minutes and reach equilibrium after 50 min. The maximum adsorption capacities of the adsorbent are in the range of 36.5-68.18 mg/g, for the 200-500 mg/L initial solution concentration.
