Fe3O4/MWCNT adsorbent was synthesized by co-precipitation method and characterized by XRD, SEM, and TGA. 94 % MG removal and 98 % RB removal were achieved in 80 min using 10 mg adsorbent, at pH 6 and 298 K. The effects of adsorbent amount, pH, initial dye concentration, contact time, and temperature were investigated. Equilibrium data were well fitted by Langmuir adsorption model and pseudo-second-order kinetic model. MG adsorption on Fe3O4/MWCNT is exothermic and RB adsorption is endothermic in nature.eninfo:eu-repo/semantics/closedAccessMagnetic separationCarbon nanotubesDye adsorptionHealth and environmental effectsRemediationArticle10.1007/s11051-014-2431-12-s2.0-849013283226Q216WOS:000335665800001Q2
