Abstract
Na–bentonite was modified via an ion-exchange reaction with hexadecyl trimethyl ammonium bromide (CTAB). X-ray diffractometer (XRD) indicated CTAB cations had exchanged with Na+ ions in Na–bentonite and the interlayer space of bentonite was increased. Batch adsorption tests were carried out to remove phenol from model wastewater using the modified bentonite, and the effect of amount of CTAB, contact time, pH, and adding quantity of modified bentonite were evaluated. The experimental results showed that the removal efficiency of phenol can be up to 81.36% under the following conditions: the amount of CTAB was 1.5 cation exchange capacity (CEC), the dosage of organic modified bentonite was 7 g/L, the adsorption time was 60 min, and the pH value was 7. The adsorption isotherms of organic modified bentonite for phenol-based wastewater met the Freundlich adsorption equation.
