This research presents adsorption potential of surfactant (sodium dodecyl sulphate; SDS) coated magnetite nanoparticles as suitable and efficient adsorbent for the removal of Basic Blue 41 (BB 41), as a cationic dye from textile’s company wastewater. The effects of various experimental parameters (e.g. initial pH of the solution, SDS amount, and ionic strength) on the adsorption efficiency of BB 41 were investigated and optimized. The result showed that kinetic of adsorption process is very fast and after 30 min equilibrium for dye adsorption could be obtained.. Equilibrium isotherm data were fitted to Langmuir and Freundlich models. The characteristic parameters for each model have been determined. The Langmuir isotherm gave the best correlation for the adsorption of the BB 41 onto the adsorbent. A superior maximum adsorption capacity (2000.6 mg g-1) was obtained for the adsorbent from the Langmuir model. Also, reuse study showed that Fe3O4 NPs could be regenerated and reused at least for six times.
