With the growth of globalization which has been the primary cause of water pollution, it is utmost necessary for us living being to have access to clean water for the purpose of drinking, washing and various other useful applications. With the purpose of future security and to restore our ecological balance, it is essential to give much significance towards the removal of unwanted toxic contaminants from our water resources. In this regard adsorptive removal of toxic pollutants from wastewater with porous adsorbent is regarded as one of the most promising way for water decontamination process. Metal organic frameworks (MOFs) comprising of uniformly arranged pores, abundant active sites and containing an easily tunable structure has aroused as a promising material for adsorbent to remove the unwanted contaminants from water sources. The adsorption of pollutants by the different MOFs surface are driven by various interactions including π-π, acid-base, electrostatic and H-bonding etc. On the other hand, the removal of various contaminants by MOFs is influenced by various factors including pH, temperature and initial concentration. In this review we will specifically discuss the adsorptive removal of different organic and inorganic pollutants present in our water systems with the use of MOFs as adsorbent along with the various factors and interaction mechanism manipulating the adsorption behaviour.
随着全球化的增长，这是水污染的主要原因，我们生物有必要获得干净的水，用于饮用、洗涤和各种其他有用的应用。为了未来的安全和恢复我们的生态平衡，必须重视从我们的水资源中去除不需要的有毒污染物。在这方面，多孔吸附剂对废水中有毒污染物的吸附被认为是水净化过程中最有前途的方法之一。金属有机骨架（MOFs）由均匀排列的孔、丰富的活性位点和可轻松调节的结构组成，已成为去除水源中不需要的污染物的有前途的吸附剂材料。不同 MOFs 表面对污染物的吸附是由各种相互作用驱动的，包括 π-π、酸碱、静电和氢键等。另一方面，MOFs 对各种污染物的去除受到各种因素的影响，包括 pH 值、温度和初始浓度。在这篇综述中，我们将专门讨论使用 MOFs 作为吸附剂从我们的水系统中去除不同的有机和无机污染物的吸附去除，以及影响吸附行为的各种因素和相互作用机制。
