Synthesis of Magnetic Modified Organobentonite as Adsorbent for Degradation of Orange II

Abstract:

Magnetic modified organobentonite (Fe₃O₄/CTAB–Bent) was synthesized by chemical co-precipitation method in which CTAB–Bent was firstly achieved via ion–exchange.The composite materials have been characterized by powder X–ray diffraction (XRD), Fourier transform infrared spectroscopy (FT–IR) and Scanning electron microscopy (SEM) . The results revealed that basal spacing of bentonite was increased through organic modification and the Fe₃O₄ particles synthesized which covering the surfaces of bentonite .Compared with natural bentonite, the adsorption capacity of Fe₃O₄/CTAB–Bent for Orange II was greatly enhanced and can be easily separated from the reaction medium by an external magnetic field after the treatment.
