As the world population continues to grow, there is also a rising concern regarding water pollution since this condition could negatively impact supply of clean water. One most recent concerns related that comes from various pharmaceuticals, in particular non-steroidal anti-inflammatory drugs (NSAIDs) they have been industrially produced at large scale and can be easily purchased as an over-the-counter medicine. Diclofenac one popular NSAIDs because its high-effectiveness, which leads excessive consumption. Consequently, presence bodies continuously increasing. An adsorption process then employed highly effective method address issue. In comparison other conventional adsorbents such activated carbon, use metal-organic frameworks (MOFs) alternative adsorbent very attractive it offer advantages tailorability high capacity. study, performance three water-stable, free-base porphyrin MOFs assembled using zirconia-based nodes, namely MOF-525, MOF-545, NU-902, for diclofenac was thoroughly investigated. Interestingly, although all are same building block similar specific surface area (based on experimental argon physisorption calculation based non-localized density functional theory), their capacity substantially different another. It found highest shown by has maximum around 792 mg g-1. This followed MOF-545 NU-902 capacities 591 486 g-1, respectively. Some possible mechanisms discussed might contribute phenomenon. Lastly, compared with studied purpose show superiority not only terms but affinity towards molecule, useful indicator real where contaminant concentration considerably low.
