多孔地质聚合物(PGs)对水中重金属离子的吸附性能与其孔隙特征密切相关。由于PGs的孔隙特征受其发泡工艺影响较大,因此,综述了几种常见的PGs发泡工艺,包括化学发泡、机械发泡、牺牲模板法和增材制造对其孔隙特征的影响,分析了孔隙特征与其吸附性能之间的关系,并在此基础上提出优化措施展望。
The adsorption performance of porous geopolymers (PGs) for heavy metal ions in water is closely related to their pore characteristics.There are significant differences in the pore characteristics of geopolymers prepared by different foaming processes.Therefore,this article reviewed the effects of several common PGs foaming processes,including chemical foaming,mechanical foaming,sacrificial template method,and additive manufacturing,on their pore characteristics.The relationship between pore characteristics and their adsorption performance was analyzed,and optimization measures were proposed based on this.
