中文摘要：

采用传统注浆法,以工业级水玻璃为碱激发剂,偏高岭土以及水为原料,以理论摩尔配比（SiO2/Na2O=1.3,Na2O/Al2O3=0.8,SiO2/Al2O3=2.96,H2O/Na2O=19）混合后经机械搅拌均匀制备得到地质聚合物浆料,注浆在直径为40 mm的圆形模具中,60℃条件下养护24 h后脱模即可得到平均孔径范围为11.88-26.82 nm的地聚物片式无机膜。研究采用扫描电镜（SEM）、紫外分光光度计、抗压强度测试、水通量测试等对地质聚合物自支撑无机膜的各项性能进行表征,由于地质聚合物自支撑无机膜具有良好的稳定性和较窄的孔径分布,使其在废水处理中表现出比有机膜更大的潜力。

英文摘要：

Geopolymer inorganic membrane was synthesised using metakaolin, water, and water-glass according to a mixing ratio model （SiO2/Na2O=1.3, Na2O/Al2O3=0.8, SiO2/Al2O3=2.96 and H2O/Na2O=19）. After mechanical stirring, the geopolymer slurry was cast in a circular mould with the diameter of 40mm, cured at 60℃ for 24 h and then demoulded. Geopolymer-based inorganic membrane formed a homogenous structure and had a narrow pore size distribution from about 11.88-26.82 nm. Scanning electron microscopy （SEM）, ultraviolet spectrophotometer, compressive strength test and water flux test characterized various properties of the geopolymer-based inorganic membrane. The geopolymer-based inorganic membrane has shown greater potential than the organic membrane for application in wastewater treatment due to its stability and narrow pore size distribution.
