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
