Water is vital for the sustenance of all forms of life. Hence, water pollution is a universal crisis for the survival for all forms of life and a hurdle in sustainable development. Textile industry is one of the anthropogenic activities that severely pollutes water bodies. Inefficient dyeing processes result in thousands of tons of synthetic dyes being dumped in water bodies every year. Therefore, the efficient removal of synthetic dyes from wastewater has become a challenging research field. Owing to their tuneable structure-property aspects, metal-organic frameworks (MOFs) have emerged as promising adsorbents for the adsorptive removal of dyes from wastewater and textile effluents. In this perspective, we highlight recent studies involving the application of MOFs for the adsorptive removal of hazardous dye molecules. We also classify the developed MOFs into cationic, anionic, and neutral framework categories to comprehend their suitability for the removal of a given class of dyes.
水是所有生命形式赖以生存的关键要素。因此，水污染是所有生命形式生存的普遍危机，也是可持续发展的一个障碍。纺织工业是严重污染水体的人为活动之一。低效的染色工艺导致每年有数千吨合成染料被倾倒入水体中。因此，从废水中高效去除合成染料成为了一个具有挑战性的研究领域。由于其可调的结构-性能方面，金属-有机骨架（MOFs）已成为从废水中和纺织废水中吸附去除染料的有前途的吸附剂。在这篇观点文章中，我们重点介绍了涉及 MOFs 用于吸附去除危险染料分子的最新研究。我们还将开发的 MOFs 分为阳离子型、阴离子型和中性骨架类别，以了解它们对去除给定类别染料的适用性。
