| Abstract: In this paper, we fabricated a high-strength self-supporting NaA zeolite membrane from a geopolymer membrane through in situ hydrothermal transformation processing. The surface and inner amorphous geopolymer membrane was converted into the zeolite crystal phase after the hydrothermal process was applied, and the volume of the micropores of the hydrothermal sample changed from 0 to 0.049 cc/g after the hydrothermal process. We preliminarily studied the practicability and preparation of a self-supporting NaA zeolite membrane with a high compressive strength (approximately 57 MPa) for desalination through a pervaporation process. The results showed that the self-supporting NaA zeolite membranes exhibited improved high sodium ion rejection (approximately 99.5%) as the thickness gradually increased to a certain value (about 9.4 mm), and the flux (0.42 kg m-2 h-1 at 25ºC) gradually increased to 3.86 kg m-2 h-1 as the pervaporation temperature increased to 90ºC. |

| 摘要：在本文中，我们用地质聚合膜经原位水温转化制造了一种高强度自身支持NaA沸石分子筛膜。在水温作用下，表面和内部无定形的地质聚合膜转变为沸石分子筛晶相，水温样品的微孔体积由0变为0.049 cc/g。我们初步测试了以高耐压强度 （近57 MPa）制备自身支持NaA沸石分子筛膜通过全蒸发作用脱盐及其可行性。结果表明这种自身支持NaA沸石分子筛膜随着厚度逐渐增加到一定值（近 9.4 mm)，当全蒸发温度有25摄氏度增加到90摄氏度，流量由0.42kg/平方米/小时逐渐增加到3.86kg/平方米/小时， 其表现出高排钠离子能力（近 99.5%)。 |
