The popularity of diclofenac, one of the highly effective non-steroidal anti-inflammatory drugs (NSAIDs), has led to its excessive consumptions. Consequently, its presence in water bodies is continually increasing and poses serious threats to ecosystems. Adsorption processes have been employed to address this issue. However, most of the commercially available adsorbents such as activated carbon, zeolite, etc. suffer from relatively low diclofenac adsorption capacity (100–200 mg g⁻¹) and slow kinetics. Herein, we explore the potential of MOF-808 as a superior adsorbent for diclofenac removal. Benefitting from its high specific surface area and large pore aperture, the maximum diclofenac adsorption capacity achieved in this study reaches 833 mg g⁻¹ with almost 95% removal within first hour. This performance is one of the highest reported adsorbents for diclofenac removal so far and has led us to have further commercial exploitation by employing a yttria-stabilised zirconia (YSZ) hollow fibre support where the MOF-808 adsorbent is deposited on its outer surface. Such a configuration is beneficial from a practical point-of-view, as it eliminates the requirement of separation of powdered adsorbents from treated water once the adsorption process finishes. Also, the hollow fibre configuration not only substantially increases the surface-area-to-volume ratio of adsorption systems, but also reduces the maldistribution of flows commonly unavoidable in conventional packed bed adsorption columns. The high-efficiency of the MOF-808 hollow fibre adsorbent is exhibited by retainment of its equilibrium adsorption capacity of 796 mg g⁻¹. More importantly, the MOF-808 hollow fibre adsorbent can withstand at least 4 adsorption-regeneration cycles without any significant reduction in the adsorption performances, indicating the potential for possible commercialisation of the MOF-808 adsorbent for diclofenac removal from water.

双氯芬酸是一种高效的非甾体类抗炎药（NSAIDs）的流行，导致其过量消费。因此，其在水体中的存在不断增加，并对生态系统构成了严重威胁。吸附过程已被用来解决这个问题。但是，大多数市售的吸附剂，例如活性炭，沸石等，都具有相对较低的双氯芬酸吸附能力（100-200 mg g ^-1）和缓慢的动力学。在本文中，我们探索了MOF-808作为去除双氯芬酸的优良吸附剂的潜力。得益于其高比表面积和大孔径，该研究中获得的最大双氯芬酸吸附容量达到833 mg g ^-1在第一个小时内去除率几乎达到95％。该性能是迄今为止报道的双氯芬酸去除率最高的吸附剂之一，通过使用氧化钇稳定的氧化锆（YSZ）中空纤维载体将MOF-808吸附剂沉积在其外表面上，使我们获得了进一步的商业开发。从实用的观点来看，这种构造是有益的，因为它消除了一旦吸附过程完成就从处理过的水中分离粉末状吸附剂的要求。而且，中空纤维的构型不仅大大增加了吸附系统的表面积与体积之比，而且还减少了常规填充床吸附塔通常无法避免的流量分布不均。^-1。更重要的是，MOF-808中空纤维吸附剂可以承受至少4个吸附-再生循环，而吸附性能没有任何显着降低，表明从水中去除双氯芬酸的MOF-808吸附剂可能有商业化的潜力。
