“…Adsorption of dyes and heavy metal using magnetically separable metal ferrite nanoparticles has been reported in many studies [29][30][31][32] Compared to other ferrites, CaFe 2 O 4 is considered the most biocompatible due to its eco-friendly and nontoxicity nature [33]. In this context, various investigations showed the successful synthesis of magnetically separable crystalline CaFe 2 O 4 nanoparticles and its potential use as an adsorbent for dyes such as reactive orange 12 (RO12) dye [34][35][36][37][38][39]. Therefore, GO can be combined with other nanomaterials such as CaFe 2 O 4 nanoparticles to form nanohybrid material, to remove contaminants from water efficiently.…”

Herein, we report the nanofabrication of magnetic calcium ferrite (CaFe2O4) with nitrogen-doped graphene oxide (N-GO) via facile ultrasonication method to produce CaFe2O4/N-GO nanocomposite for the potential removal of reactive orange 12 (RO12) dye from aqueous solution. The successful construction of the nanocomposite was confirmed using different characterization techniques including scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform-infrared spectroscopy (FT-IR), and X-ray diffraction (XRD). The magnetic properties were studied using vibrating sample magnetometer (VSM) indicating ferromagnetic behavior of the synthesized materials that facilitate their separation using an external magnetic field after adsorption treatment. The addition of N-GO to CaFe2O4 nanoparticles enhanced the BET surface area from 24 to 52.93 m2/g as resulted from the N2 adsorption-desorption isotherm. The adsorption of the synthesized nanomaterials is controlled by several parameters (initial concentration of dye, contact time, adsorbent dosage, and pH), and the RO12 dye removal on the surface of CaFe2O4 nanoparticles and CaFe2O4/N-GO nanocomposite was reached through the chemisorption process as indicated from the kinetic study. The adsorption isotherm study indicated that the adsorption process of RO12 dye was best described through the Langmuir isotherm approving the monolayer adsorption. According to the Langmuir model, the maximum adsorption capacity for RO12 was 250 and 333.33 mg/g for CaFe2O4 nanoparticles and CaFe2O4/N-GO nanocomposite, respectively. The adsorption capacity offered by CaFe2O4/N-GO nanocomposite was higher than reported in the literature for adsorbent materials. Additionally, the regeneration study indicated that CaFe2O4/N-GO nanocomposite is reusable and cost-effective adsorbent. Therefore, the nanofabricated CaFe2O4/N-GO hybrid material is a promising adsorbent for water treatment.

“…For this purpose, some methods including oxidation, ozonation, electrolysis, reverse osmosis, coagulation/flocculation, adsorption, filtration and biological treatment are used (Gupta and Suhas, 2009;Koprivanac and Kusic, 2009;Saratale et al, 2011;Gupta and Ali, 2013). Among these, adsorption is an attractive way to remove dyes from aqueous effluents (Piccin et al, 2011;Dotto and Pinto, 2011a;Foletto et al, 2013;Ghaedi et al, 2013;Akkaya and Güzel, 2014;Reddy et al, 2014). Simplicity of design, low-cost, high removal efficiency, ease of operation and availability are the main advantages of adsorption (Gupta and Ali, 2013).…”

The adsorption of FD&C red 2 and FD&C yellow 5 onto chitosan films was evaluated by equilibrium isotherms, thermodynamics and kinetic studies. The effects of temperature (298-328 K), initial dye concentration (50-300 mg L -1 ), stirring rate (50-350 rpm) and contact time (0-120 min) were investigated at pH of 2.0 and 100 mg L -1 of chitosan films. The dyes concentration was determined by spectrophotometry. Freundlich and Langmuir models were used to represent the equilibrium data. The Langmuir model was the more adequate to represent the equilibrium data (R 2 >0.99 and average relative error<2.50%) and the maximum adsorption capacities were 494.13 mg g -1 and 480.00 mg g -1 for FD&C red 2 and FD&C yellow 5, respectively, obtained at 298 K. The R L values ranged from 0.044 to 0.145. The adsorption was exothermic, spontaneous and favorable.For the FD&C red 2, 90% of saturation was attained at 120 min and the Elovich model was the more appropriate. For the FD&C yellow 5, 95% of saturation was attained at 20 min and the pseudo first-order model was the more adequate to fit the kinetic data.Chitosan films were easily separated from the liquid phase after the adsorption process, Downloaded by [Selcuk Universitesi] at 00:18 27 December 2014 ACCEPTED MANUSCRIPT ACCEPTED MANUSCRIPT 2providing benefits for industrial applications, and its application range can be extended for azo dyes.
