AI Article Synopsis
- The study explores the effectiveness of using heterogeneous Advanced Oxidation Processes with a Metal-Organic Framework (MOF), specifically Basolite F-300, as a catalyst to remove pharmaceutical pollutants and pathogens from synthetic wastewater.
- By optimizing the concentrations of peroxymonosulfate (PMS) and Basolite F-300 through Central Composite Experimental Design, researchers found that increasing these concentrations significantly decreased treatment time for the degradation of the pharmaceutical antipyrine.
- The PMS-Basolite F-300 system demonstrated stability and effectiveness over at least four treatment cycles without losing its ability to disinfect and degrade harmful contaminants.
Article Abstract
In this study, the removal of persistent emerging and dangerous pollutants (pharmaceuticals and pathogens) in synthetic wastewater was evaluated by the application of heterogeneous Advanced Oxidation Processes. To do that, a Metal-Organic Framework (MOF), Basolite F-300 was selected as a catalyst and combined with peroxymonosulfate (PMS) as oxidants in order to generate sulphate radicals. Several key parameters such as the PMS and Basolite F-300 concentration were evaluated and optimized using a Central Composite Experimental Design for response surface methodology for the inactivation of . The assessment of the degradation of an analgesic and antipyretic pharmaceutical, antipyrine, revealed that is necessary to increase the concentration of PMS and amount of Basolite F-300, in order to diminish the treatment time. Finally, the PMS-Basolite F-300 system can be used for at least four cycles without a reduction in its ability to disinfect and degrade persistent emerging and dangerous pollutants such as pharmaceuticals and pathogens.

In recent years, heterogeneous electro-Fenton processes have gained considerable attention as an alternative to homogeneous processes. In this context, the aim of this study is the use of a commercial iron metal-organic framework (Fe-MOF), Basolite® F-300, as a base material for the design of a heterogeneous electro-Fenton treatment system for the removal of antipyrine. Initially, the catalyst was applied as powder in aqueous solution and three key parameters of the electro-Fenton process (pH, Fe-MOF concentration and current density) were evaluated and optimized by a Central Composite Design Face Centred (CCD-FC) using antipyrine removal and energy consumption as response functions.

Heteropolyacid encapsulation into the MOF: influence of acid particles distribution on ethanol conversion in hybrid nanomaterials.

Hybrid nanomaterials comprising tungsten heteropolyacid (HPW) and iron-based MOF Basolite™ F 300 used as a support were obtained by post-synthesis combination of the two components. Samples with increasing HPW loading (20, 50, and 80 wt%) were characterised by appropriate physicochemical methods, including nitrogen sorption, electron microscopy imaging, FT-IR spectroscopy, sorption microbalance and catalytic tests. The acidic protons of the tungsten-based heteropolyacid catalysed ethanol conversion depending on location of HPW at either internal or external surfaces of the commercial Basolite™ F 300.
