In this work, established treatment processes for microplastics (MPs) and nanoplastics (NPs) in water as well as developed analytical techniques for evaluation of the operation of these processes were reviewed. In this regard, the strengths and limitations of different qualitative and quantitative techniques for the analysis of MPs and NPs in water treatment processes were first discussed. Afterward, the MPs and NPs treatment processes were categorized into the separation and degradation processes and the challenges and opportunities in their performance were analyzed. The evaluation of these processes revealed that the MPs or NPs removal efficiency of the separation and degradation processes could reach up to 99% and 90%, respectively. It can be concluded from this work that the combination of separation and degradation processes could be a promising approach to mineralize MPs and NPs in water with high efficiency.
在这项工作中，我们回顾了已建立的水中微塑料（MPs）和纳米塑料（NPs）的处理工艺，以及开发用于评估这些工艺运行情况的分析技术。在这方面，首先讨论了不同定性和定量技术在水处理工艺中分析 MPs 和 NPs 的优缺点。然后，将 MPs 和 NPs 的处理工艺分为分离和降解工艺，并分析了它们在性能方面的挑战和机遇。对这些工艺的评估表明，分离和降解工艺对 MPs 或 NPs 的去除效率分别可达 99%和 90%。从这项工作可以得出结论，将分离和降解工艺相结合可能是一种高效将水中 MPs 和 NPs 矿化的有前途的方法。
