三氯乙烯(TCE)对地下水的污染提出了紧迫的环境挑战,并产生了深远的影响。传统的修复方法在有效解决TCE污染方面显示出局限性。本研究回顾了常规修复技术的局限性,并研究了基于氧化剂的控释材料的应用,包括封装,已加载,和自2000年以来的凝胶基高锰酸钾。此外,它检查了还原剂控释材料和电子供体释放材料,例如原硅酸四丁酯(TBOS)和聚羟基丁酸酯(PHB)。研究结果表明,控释材料为增强TCE降解和促进地下水恢复提供了有希望的途径。本研究最后强调了未来的研究方向和控释材料在解决TCE污染挑战方面的潜力。
Groundwater contamination by trichloroethylene (TCE) presents a pressing environmental challenge with far-reaching consequences. Traditional remediation methods have shown limitations in effectively addressing TCE contamination. This study reviews the limitations of conventional remediation techniques and investigates the application of oxidant-based controlled-release materials, including encapsulated, loaded, and gel-based potassium permanganate since the year 2000. Additionally, it examines reductant controlled-release materials and electron donor-release materials such as tetrabutyl orthosilicate (TBOS) and polyhydroxybutyrate (PHB). The findings suggest that controlled-release materials offer a promising avenue for enhancing TCE degradation and promoting groundwater restoration. This study concludes by highlighting the future research directions and the potential of controlled-release materials in addressing TCE contamination challenges.
