摘要/Abstract

摘要：

以丁胺和正十二醇为混合模板剂, 采用共沉淀法制备了介孔纳米CuAl₂O₄. 用X射线粉末衍射(XRD)、傅里叶变换红外(FTIR)光谱、N₂吸附-脱附对产物的结构进行了表征. 采用连续在线原位衰减全反射傅里叶变换红外(ATR-FTIR)光谱技术研究了水溶液中丁基和辛基黄药在介孔CuAl₂O₄表面的吸附. 随着吸附时间的延长,1200 和1040 cm^-1两处黄药特征峰的高度逐渐增加, 根据1200 cm^-1处C-O-C伸缩振动峰的变化来评价黄药在CuAl₂O₄表面的吸附动力学过程. 结果表明, 介孔纳米CuAl₂O₄对黄药有很强的吸附能力, 在100 min 的时间内, CuAl₂O₄样品对丁基和辛基黄药的吸附量分别达到了236 和300 mg·g^-1, 且属于化学吸附. 对实验数据进行理论模拟, 发现吸附过程更接近于拟二级吸附动力学方程.

Abstract:

In this study, mesoporous nano CuAl₂O₄ was synthesized through a coprecipitation method using simple mixed templates consisting of butylamine and dodecanol. The sample was characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and nitrogen adsorptiondesorption techniques. The absorption of butyl and octyl xanthate from aqueous solution onto the synthesized mesoporous CuAl₂O₄ solid surfaces was studied by a continuous, online, in situ attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR) technique. The CuAl₂O₄ membrane used in the adsorption experiments was prepared on a germanium internal reflection element using the chemical bath deposition method. During the adsorption process, the characteristic peak height of xanthate at 1200 and 1040 cm^-1 emerged and gradually increased. By monitoring changes in the peak height at 1200 cm^-1, which was assigned to the stretching vibration caused by C-O-C of the adsorbed xanthate molecules, the adsorption kinetics were studied. The adsorption results show that mesoporous CuAl₂O₄ has a high chemisorption capacity for xanthate, which reaches 236 and 300 mg·g^-1 for butyl and octyl xanthate, respectively, within 100 min. The adsorption kinetics can be described by a pseudo-second-order reaction model.
