One of the biggest global challenges in mining industry is managing risks associated with contamination by potentially toxic elements (PTEs) resulting from their activity. The oxidation sulfides main cause polluted mine drainage through leaching PTEs waste and galleries to water systems. Mine can be highly acidic often has a high concentration PTEs, particularly arsenic, one environment’s most elements. endanger ecosystem’s equilibrium raise worries about human animal health. Some species algae which naturally present waters, such as Spirogyra sp. And Chlorella sp., have capacity for absorbing wastewater may thrive harsh environments. As result, algal-based systems bioremediation were studied carefully analyzed, since remove heavy metals hazardous contaminants already been shown previous studies. Biofuels derived microalgal biomasses are viable alternative fossil fuels that lead circular bioeconomy.

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.
