A novel sulfonated cellulose-magnetite (Fe 3 O 4 ) composite sorbent was prepared and applied for the removal of Cu 2+ ions from an aqueous solution. It was characterized by infrared spectroscopy, X-ray fluorescence, elemental analysis, SEM, VSM and X-ray photoelectron spectroscopy. The effect of the sorbent dose, initial solution pH, and temperature on Cu 2+ removal were studied. The removal of the Cu 2+ was completed in 15 min, and the sorption kinetics of Cu 2+ was found to follow a pseudo-second-order kinetic model. An equilibrium test demonstrated that sorption of Cu 2+ onto a hybrid sorbent agreed well with the Langmuir adsorption model for a maximum adsorption capacity of 4.2 mg/g. Moreover, the optimum pH for Cu 2+ removal was found to be ≥4. Furthermore, the thermodynamic parameters reveal the feasibility, spontaneity and endothermic nature of the sorption process. In addition, Cu 2+ ions can be desorbed from the sorbent with a 0.5 M H 2 SO 4 solution.
