摘要

开发具有成本效益和高性能的废水处理技术对于实现可持续经济至关重要。在现有的各种水处理方法中,吸附被公认为是去除一系列污染物的有效而直接的方法。凝胶材料,尤其是水凝胶和气凝胶,因其独特的性能而引起了研究人员的极大兴趣。例如,水凝胶因其可再生和重复使用、易于分离和处理以及适合大规模应用而备受关注。此外,水凝胶的低成本、高吸水性和对环境保护的贡献也是其重要优势。另一方面,气凝胶具有热导率低、透明度高、柔韧性好、孔隙率高、机械强度高、重量轻、表面积大和介电常数超低等特点。本综述对现有文献进行了全面分析,重点介绍了在这些材料的分类、制备、表征和关键特性方面存在的知识空白。此外,还讨论了水凝胶和气凝胶在水处理方面的潜在应用,特别是在去除染料、重金属以及各种有机和无机污染物等污染物方面的应用。

Gels for Water Remediation: Current Research and Perspectives.

The development of cost-effective and high-performance technologies for wastewater treatment is essential for achieving a sustainable economy. Among the various methods available for water remediation, adsorption is widely recognized as an effective and straightforward approach for removing a range of pollutants. Gel materials, particularly hydrogels and aerogels, have attracted significant research interest due to their unique properties. Hydrogels, for instance, are noted for their ability to be regenerated and reused, ease of separation and handling, and suitability for large-scale applications. Additionally, their low cost, high water absorption capacity, and contribution to environmental protection are important advantages. Aerogels, on the other hand, are distinguished by their low thermal conductivity, transparency, flexibility, high porosity, mechanical strength, light weight, large surface area, and ultralow dielectric constant. This review provides a comprehensive analysis of the current literature, highlighting gaps in knowledge regarding the classification, preparation, characterization, and key properties of these materials. The potential application of hydrogels and aerogels in water remediation, particularly in removing contaminants such as dyes, heavy metals, and various organic and inorganic pollutants, is also discussed.
