The increased industrialization and urbanization generate a larger quantity of effluent that is discharged into the environment regularly. Based on the effluent composition produced from various industries, the number of hazardous substances such as heavy metals, hydrocarbons, volatile organic compounds, organic chemicals, microorganisms introduced into the aquatic systems vary. The conventional wastewater treatment systems do not meet the effluent standards before discharge and require a different treatment system before reuse. Adsorption is an eco-friendly technique that uses selective adsorbents to remove hazardous pollutants even at microscale levels. MXene, a 2-Dimensional nanomaterial with resplendent properties like conductivity, hydrophilicity, stability, and functionalized surface characteristics, is found as a potential candidate for pollutant removal systems. This review discusses the fabrication, characterization, and application of MXene based nanoparticles to remove many pollutants in water treatment systems. The improvement in surface properties and adsorption capacity of MXene based NPs, when modified using different modification agents, has also been discussed. Their feasibility in terms of economic and environmental aspects has been evaluated to understand their scope for practical application in large-scale industries. The challenges towards the synthesis and toxicity's importance have been discussed, with the appropriate recommendations.
工业化和城市化的发展导致了更多的废水排放到环境中。根据不同工业产生的废水成分，进入水系统的有害物质（如重金属、碳氢化合物、挥发性有机化合物、有机化学品、微生物）的数量也有所不同。传统的废水处理系统在排放前不符合排放标准，需要在再利用前采用不同的处理系统。吸附是一种环保技术，它使用选择性吸附剂来去除有害物质，即使在微观水平上也是如此。MXene 是一种二维纳米材料，具有导电性、亲水性、稳定性和功能化表面特性等卓越性能，被认为是去除污染物系统的潜在候选材料。本综述讨论了 MXene 基纳米粒子的制备、表征及其在水处理系统中去除多种污染物的应用。还讨论了使用不同改性剂对 MXene 基 NPs 的表面性能和吸附能力的改善。评估了它们在经济和环境方面的可行性，以了解其在大规模工业中实际应用的范围。还讨论了合成方面的挑战和毒性的重要性，并提出了适当的建议。
