利用 FT- IR和 XRD两种光谱学方法 ,对阳离子表面活剂十六烷基三甲基溴化铵( CTAB)在高岭土、石英砂和蒙脱土颗粒上的吸附进行了光谱学表征 .实验结果表明 ,光谱分析能够直观地反映矿物颗粒对活性剂的吸附、定性的确定不同矿物粒子吸附量的相对大小和吸附表面活性剂造成的矿物结构的变化
The adsorption of cetyltrimethylammonium bromide (CTAB) on kaolin, quartz sand and montmorillonite particles was characterized by FT-IR and XRD spectroscopy. The results show that the spectral analysis can intuitively reflect the adsorption of mineral particles on the active agent, qualitatively determine the relative sizes of different mineral particles adsorbed and the change of the mineral structure caused by the adsorbed surfactant
