陶瓷基分子筛膜的结构调控及脱盐性能
Structural regulation and desalination performance of ceramic-based zeolite membranes
摘要
Abstract
The dip-coating method was employed to load a NaA seed layer on the surface of alumina oxide ceramic carrier.The NaA zeolite membrane was then fabricated by a hydrothermal synthesis method.The effect of reaction time on membrane structure and pervaporation desalination performance was investigated.The experimental results indicate that the reaction time significantly affects both the thickness and average growth rate of NaA zeolite membrane.At a reaction time of 12 h and a synthesis temperature of 80℃,a well-synthesized,defect-free,and uniformly thick zeolite membrane is formed.With a 35 g/L NaCl solution as feed,the membrane exhibits a water flux of 5.28 L/(m2·h),with salt rejection exceeding 99.9%at an operating temperature of 70℃.When the NaCl solution mass concentration is further increased to 95 g/L,the membranes maintain robust operational stability,with salt rejection still exceeding 99.9%,demonstrating a distinct competitive advantage in the field of pervaporation desalination.关键词
