The presence of persistent organic pollutants (POPs) in the aquatic environment is causing widespread concern due to their bioaccumulation, toxicity, and possible environmental risk. These contaminants are produced daily in large quantities and released into water bodies. Traditional wastewater treatment plants are ineffective at degrading these pollutants. As a result, the development of long-term and effective POP removal techniques is critical. In water, adsorption removal and photocatalytic degradation of POPs have been identified as energy and cost-efficient solutions. Both technologies have received a lot of attention for their efforts to treat the world's wastewater. Photocatalytic removal of POPs is a promising, effective, and long-lasting method, while adsorption removal of persistent POPs represents a simple, practical method, particularly in decentralized systems and isolated areas. It is critical to develop new adsorbents/photocatalysts with the desired structure, tunable chemistry, and maximum adsorption sites for highly efficient removal of POPs. As a class of recently created multifunctional porous materials, Metal-organic frameworks (MOFs) offer tremendous prospects in adsorptive removal and photocatalytic degradation of POPs for water remediation. This review defines POPs and discusses current research on adsorptive and photocatalytic POP removal using emerging MOFs for each type of POPs.
持久性有机污染物 (POPs) 在水环境中的存在引起了广泛关注,因为它们具有生物累积性、毒性和潜在的环境风险。这些污染物每天大量产生并释放到水体中。传统的废水处理厂无法有效降解这些污染物。因此,开发长期有效的 POP 去除技术至关重要。在水中,吸附去除和光催化降解 POPs 已被确定为节能且具有成本效益的解决方案。这两种技术都因其处理世界范围内废水的努力而受到了广泛关注。光催化去除 POPs 是一种很有前途、有效且持久的方法,而吸附去除持久性 POPs 则代表了一种简单、实用的方法,特别是在分散系统和偏远地区。开发具有所需结构、可调化学性质和最大吸附位点的新型吸附剂/光催化剂对于高效去除 POPs 至关重要。作为一类最近创建的多功能多孔材料,金属有机骨架 (MOFs) 在用于水修复的 POPs 的吸附去除和光催化降解方面具有巨大的前景。本综述定义了 POPs,并讨论了使用新兴 MOFs 进行每种类型的 POPs 的吸附和光催化 POP 去除的当前研究。
