Tóm tắt

In the present work, the Al-bentonite was prepared by the modification of Wyoming bentonite with cation aluminium by ultrasound-assisted cation exchange. X-ray diffraction (XRD), infrared spectroscopy (FTIR), and nitrogen adsorption/desorption isotherms were utilized to characterize the modified bentonite. The Al-bentonite was employed for the removal of fuchsin acid from aqueous solution. Fuchsin acid adsorption followed the pseudo-second-order kinetic model. The determined activation energy of this fuchsin acidadsorption was 5.17 kJ/mol.
