We reported a facile strategy for assembling NiCoAl-layered double hydroxide/multi-walled carbon nanotubes (NiCoAl-LDH/MWCNTs) nanohybrid through noncovalent bonds. The assembling process and structures of exfoliated LDH/CNTs nanohybrid were characterized by scanning electron microscopy (SEM), powder X-ray diffraction (XRD), thermogravimetric analysis (TGA), Fourier transform infrared (FT-IR) and specific surface area measurement. The effect of nanohybrid dosage, pH and contact time on the adsorption process was optimized and modeled. The removal percentage of dye by nanohybrid was 65% and the maximum adsorption capacity (q(m)) was 196.08 mg g(-1) at the optimized conditions. Isotherm and kinetic of the adsorption process were investigated. (C) 2014 The Korean Society of Industrial and Engineering Chemistry. Published by Elsevier B.V. All rights reserved.
