摘要
采用分光光度法探究了天然沸石与NaCl改性沸石对有机染料的吸附性能,以此建立了其吸附动力学方程,并采用扫描电镜对吸附前后沸石的表面形貌进行了表征,揭示了吸附材料表面结构与其吸附性能间的联系。本教学实验的开展,启发了学生如何采用合适的实验手段来建立并验证相关的吸附动力学方程,加深了学生对材料表面结构与性能联系的认知,强化了学生对界面化学相关理论的理解,有利于创新人才的培养。
The adsorption properties of natural and NaCl-modified zeolites to organic dyestuff were studied by spectrophotometry, and the adsorption kinetics equation was also established. The surface morphology of the zeolite was analyzed by scanning electron microscope for understanding the relationship between the surface structure of the adsorbent and its absorbability. The ability how to use appropriate methods to establish and verify the relevant adsorption kinetic equations for students will be inspired by carrying out the teaching experiment. In addition, the knowledge about the relationship between the surface structure of mineral materials and performance will be further consolidated, enhancing the understanding about the interface chemistry theory, which will be conducive to the cultivation of innovative talents.
