Environmental pollution has intensified and accelerated due to a steady increase in the number of industries, and finding methods to remove hazardous contaminants, which can be typically divided into inorganic and organic compounds, have become inevitable. One of the widely used water treatment technologies is adsorption and various kinds of adsorbents for the removal of inorganic and organic contaminants from water have been discovered. Recently, MXene, as an emerging nanomaterial, has gained rapid attention owing to its unique characteristics and various applicability. Particularly, in the area of adsorptive application, MXene and MXene-based adsorbents have shown great potential in a large number of studies. In this regard, a comprehensive understanding of the adsorptive behavior of MXene-based nanomaterials is necessary in order to explain how they remove inorganic and organic contaminants in water. Adsorption by MXene-based adsorbents tends to be highly influenced by not only the physicochemical properties of these adsorbents but also water quality, such as pH value, temperature, background ion, and natural organic matter. Therefore, in this review paper, the effect of various water quality on the adsorption of inorganic and organic contaminants by various types of MXene and MXene-based adsorbents is explored. Furthermore, this review also covers general trends in the synthesis of MXene and regeneration of MXene-based adsorbents in order to assess their stability.
由于工业数量的稳步增加，环境污染加剧和加速，寻找方法去除危险污染物已成为必然，这些污染物通常可分为无机化合物和有机化合物。吸附是一种广泛使用的水处理技术，人们发现了各种用于去除水中无机和有机污染物的吸附剂。最近，MXene 作为一种新兴的纳米材料，由于其独特的特性和各种适用性而受到了迅速关注。特别是在吸附应用领域，MXene 和基于 MXene 的吸附剂在大量研究中显示出了巨大的潜力。在这方面，为了解释它们如何去除水中的无机和有机污染物，有必要全面了解基于 MXene 的纳米材料的吸附行为。基于 MXene 的吸附剂的吸附不仅受这些吸附剂的物理化学性质的影响，还受水质（如 pH 值、温度、背景离子和天然有机物）的影响。因此，在这篇综述论文中，探讨了各种水质对各种类型的 MXene 和基于 MXene 的吸附剂吸附无机和有机污染物的影响。此外，本综述还涵盖了 MXene 的一般合成趋势和基于 MXene 的吸附剂的再生，以评估它们的稳定性。
