Abstract [en]

The feasibility of nano-Al2O3 for bromate removal from aqueous solution was assessed in the present study. Batch sorption experiments were performed to examine the influence of various experimental parameters such as contact time, initial bromate concentration, temperature, and pH on the sorption of bromate on nano-Al2O3. Kinetic data revealed that the uptake rate of bromate was rapid in the beginning and 50% adsorption was completed within 10 min and equilibrium was achieved within 120 min. Pseudo-second-order kinetic model was fitted well with the kinetics of the sorption process. The sorption potential of nano-Al2O3 for bromate removal was similar to 6.0mg g(-)1. The adsorption was found to be an endothermic process and data conform to the Langmuir model.
