The surface modification of NFN using sodium dodecyl sulfate (SDS) was studied. Dye removal ability of NFN and surface modified NFN (NFN-SDS) was investigated. Physical characteristics of NFN-SDS were studied using Fourier transform infrared (FTIR), scanning electron microscopy (SEM) and X-ray diffraction (XRD). Basic Blue 41 (BB41), Basic Green 4 (BG4) and Basic Red 18 (BR18) were used as model compounds. The kinetic and isotherm of dye adsorption were studied. The effects of operational parameter (adsorbent dosage, pH and salt) on dye removal were evaluated. Adsorption kinetic of dyes was found to conform to pseudo-second-order kinetics. The maximum dye adsorption capacity (Q 0 ) was 0.50mg/g BB41, 0.41mg/g BG4 and 0.25mg/g BR18 for NFN and 111mg/g BB41, 17mg/g BG4 and 44mg/g BR18 for NFN-SDS. It was found that dye adsorption onto NFN-SDS followed Langmuir isotherm. The thermodynamic data showed that dye adsorption onto NFN-SDS was spontaneous, endothermic, and a physisorption reaction. The results showed that the NFN-SDS being a magnetic adsorbent might be a suitable alternative to remove dyes from colored aqueous solutions.
