Abstract:

Reductive materials hold significant applicative value in the halogenated solvents contaminated groundwater remediation, yet their practical application faces hurdles such as limited migration, low efficacy, and high costs. This review summarizes the current status of halogenated solvent contaminations and advancements in research on reductive remediation materials, as well as their applications in the remediation of halogenated solvent pollution. Describing the potential and challenges these materials pose in terms of improving repair efficiency and cost reduction, this review aims to scrutinize the pros and cons of existing technologies and simultaneously explore possible directions for future advancements. To further enhance the efficacy of halogenated solvent pollution remediation, there should be a deeper investigation into modified reductive agents to augment their reactivity and migration capabilities. Additionally, there is a need to strengthen coupling studies between material technologies and optimize construction processes to reduce remediation costs and improve the feasibility of engineering implementation. Moreover, attention must be directed towards the environmental impact during the remediation process to ensure the green and sustainable development of the technology. Through these comprehensive measures, it is anticipated that halogenated solvent pollution remediation technology will progress toward a more efficient and environmentally friendly phase.
