Adsorption of Phenol on CTAB Modified Fe Pillared Bentonite

Abstract

Abstract: In order to study the adsorption performance of phenolic wastewater by bentonite, the cetyltrimethylammonium bromide (CTAB) modified Fe pillared bentonite was prepared from sodium bentonite, which was pre-modified by hydroxyl-Fe pillared then modified by cetyltrimethylammonium bromide. The structure of modified bentonite was characterized by X-ray diffraction(XRD), Fourier transform infrared spectroscopy (FT-IR) and field emission scanning electron microscopy (FESEM). The effects of adsorbent dosage, adsorption time, adsorption temperature, initial phenol concentration and pH value on the adsorption quantity were investigated, and the thermodynamics and kinetics laws of adsorption were discussed. The results show that the CTAB can insert into the interlayer and surface of the Fe pillared bentonite. When the adsorbent dosage is 3 g·L^-1, adsorption time is 60 min, adsorption temperature is 25 ℃, initial phenol concentration is 300 mg·L^-1, and pH value is 7, the phenol adsorption quantity is 29.7 mg·g^-1. The adsorption process conforms to the pseudo-second-order kinetics model and the isothermal adsorption curve can be described by the Freundlich model.

Key words: cetyltrimethylammonium bromide, Fe pillared, bentonite, phenol, adsorption
