Advanced oxidation processes (AOPs) based on H2O2 are considered effective strategies to remove emerging organic pollutants from water bodies. In this work, Fenton-like Fe-based catalysts were fabricated through a simple hydrothermal calcination method. Fe was immobilized within carbon nitride with structure of accordion-like hollow nanotubes enriched open chinks (atCN). The Fe-atCN employed for reactions degrade ranitidine (RAN). Due the unique atCN substrate and Fe–N interactions established between highly dispersed sites matrix, 3.4Fe-atCN/H2O2 system able completely eliminate RAN 30 min at an initial pH 3 (k = 0.143 min–1).

The ubiquitous presence of pharmaceutical pollutants in the environment significantly threatens human health and aquatic ecosystems. Conventional wastewater treatment processes often fall short effectively removing these emerging contaminants. Therefore, development high-performance adsorbents is crucial for environmental remediation. This research utilizes molecular simulation to explore potential novel modified metal-organic frameworks (MOFs) pollutant removal, paving way design efficient strategies. Utilizing UIO-66, a robust MOF, as base material, we developed UIO-66 functionalized with chitosan (CHI) oxidized (OCHI). These MOFs' physical chemical properties were first investigated through various characterization techniques. Subsequently, dynamics (MDS) Monte Carlo (MCS) employed elucidate adsorption mechanisms rosuvastatin (ROSU) simvastatin (SIMV), two prevalent pollutants, onto nanostructures. MCS calculations demonstrated significant enhancement energy by incorporating CHI OCHI into UIO-66. increased ROSU from -14,522 -16,459 kcal/mol SIMV -17,652 -21,207 kcal/mol. Moreover, MDS reveals rejection rates neat be at 40%, rising 60 70% OCHI. Accumulation increase 4 Å 6 9 UIO-CHI UIO-OCHI. Concentration analysis shows surges 50 90%, accumulation increasing 11 Functionalizing enhanced capacity selectivity SIMV. Abundant hydroxyl amino groups facilitated strong interactions, improving performance over that unmodified Surface functionalization plays vital role customizing MOFs removal. insights guide next-gen adsorbent development, offering high efficiency treatment.
