地质聚合物用于废水处理的现状与发展趋势研究——基于文献计量分析

The current status and development trend of geopolymers used in wastewater treatment based on bibliometric analysis

地质聚合物是一种具有三维网状类分子筛结构的非晶态或半晶态的胶凝材料.由于其具有良好的物理和化学稳定性、多孔结构和离子交换性能,地质聚合物对重金属、阳离子染料等污染物有显著的去除效果,在废水处理中展现出广阔的应用前景.本文基于文献计量学的方法分析了自1998年以来国内外有关地质聚合物用于废水处理的1067篇文献,梳理了该领域的发展规律和发展趋势.对地质聚合物在吸附、固化、光催化、膜分离等水处理技术中的应用现状和存在的问题进行了总结与分析;对多孔地质聚合物、赤泥基地质聚合物等新兴研究热点进行了讨论.最后提出在未来的研究中,需要关注地质聚合物的原料与合成、各种水处理技术的联用以及地质聚合物在实际污水中的应用.

Geopolymer is an amorphous or semi-crystalline cementing material with a three-dimensional network-like molecular sieve structure.Due to its good physical and chemical stability,porous structure and ion exchange properties,geopolymer has significant removal effects on pollutants such as heavy metals and cationic dyes,and has shown broad application prospects in wastewater treatment.This article analyzes 1067 domestic and overseas references on the use of geopolymer for wastewater treatment since 1998 using bibliometric methods,and summarizes the development laws and trends in this field.The application status and existing problems of geopolymer in wastewater treatment technologies such as adsorption,solidification,photocatalysis,and membrane separation were summarized and analyzed;the emerging research hotspots such as porous geopolymer and red mud-based geopolymer were discussed.Finally,it is proposed that in future research,attention should be paid to the raw materials and synthesis of geopolymers,the combination of various water treatment technologies,and the application of geopolymers in actual wastewater treatment.
