摘要：
Zirconium/titanium-pillared montmorillonite (Zr/Ti-MMT) was prepared via inserting zirconium/titanium polyhydroxy cations into the interlayer spaces of Na-montmorillonite (Na-MMT) as an adsorbent for adsorption of nitrobenzene in wastewater. Zr/Ti-MMT was characterized by X-ray diffraction, Fourier transform infrared spectroscopy, and specific surface area measurement. The adsorption performance of Zr/Ti-MMT on nitrobenzene in wastewater was investigated. The results show that Zr/Ti-MMT mainly consists of narrow mesopores and micropores, the interplanar spacing (d(001)) is 3.29 nm, the specific surface area is 115.4 m2/g and the average pore size is 4.35 nm. The removal rate of nitrobenzene reaches the maximum value, the adsorption quantity (qe) and removal rate are 17.59 mg/g and 87.94%, respectively, when Zr/Ti-MMT is 0.1 g, the initial concentration of nitrobenzene is 40 mg/L and the adsorption temperature is 45℃. It is indicated that the adsorption by Zr/Ti-MMT belongs to a physical adsorption, and follows the Langmuir isothermal model. The adsorption of Zr/Ti-MMT on nitrobenzene is a spontaneous process of heat absorption and entropy increase, and the adsorption process fits the first-order kinetic model. © 2019, Editorial Department of Journal of the Chinese Ceramic Society.
