摘要:

介绍一个研究型综合实验——二次生长法NaA沸石分子筛膜的合成与表征。实验预先利用热浸渍法在α-Al2O3多孔载体管外表面引入NaA沸石分子筛晶种,再通过二次生长法合成NaA沸石分子筛膜。用扫描电子显微镜和X射线衍射仪表征载体管和NaA沸石分子筛及膜的形貌和结构,并利用渗透蒸发乙醇脱水膜分离装置测试膜的分离性能。通过本实验使学生了解膜分离技术这一科学前沿领域,激发学生对科学研究的兴趣,培养学生的科研探究能力。本实验涵盖合成、表征及性能测试,知识要点多、学科覆盖面广,有利于提升学生的实践操作能力、创新意识和综合运用知识的能力。

Abstract:

A research-based comprehensive experiment was introduced:synthesis and characterization of NaA zeolite membranes prepared by the secondary growth method. NaA zeolite crystals were introduced into the outer surface of α-Al2O3 porous tubes, then NaA zeolite membranes were prepared by the secondary growth method. The morphology and structure of the support, the NaA zeolite crystals and membranes were characterized by SEM and XRD, and the separation properties of the membranes were tested by pervaporation separation device for dehydration of ethanol. Through this experiment, students can understand membrane separation technology that is the frontier of scientific research, which arouses students' interest in scientific research and cultivates students' research ability. Moreover, this experiment covers synthesis, characterization and performance test, which contains more knowledge points in wider coverage of disciplines. It is helpful to foster students' innovative consciousness and practical skills, as well as promoting their integrative skills of applying knowledge.

Key words: Research-based comprehensive experiment, Secondary growth method, NaA zeolite membrane
