Antibacterial of PSf substrate and PA active layer of TFN membrane made by POM/3-API hybrid in situ FO separation performance and photo-degradation of organic pollutant

Abstract

Membrane bacterial studies are stable in modified FO membrane that shows superior antibacterial activity against Tetrasphaeria (minimal inhibitory concentration (MIC) = 0.00350, 0.11 μg/mL). Due to augmented interventions of the containments in the water resources, essential novel hybrids construct of polyoxometalate with imidazole for the separation process and photo catalytic degradation of organic pollutants have been recognized and scouted in this paper. This work demonstrated the separation and photocatalytic extraction of the organic pollutants from the potable and waste water using organo-polyoxometalate ionic salts as hybrids designated as polyoxometalate with 3-(aminopropyl) imidazole (POM/3-API). Hybrid materials are strategically prepared in one-pot via counter acidic proton exchange between POM (O- ions) which tends to move towards N- containing organic molecules, which are doped with manganese (IV) ions. Scanning Electron Microscope (SEM) studies show physico-chemical adsorption of the hybrids, PSf substrate and on PA layer of membranes, proving the multifunctional surface characteristics morphological formation. In addition, POM/3-API hybrids were synthesized via shock acoustic that reveals higher permeate flux through separation process and almost disappears (PAPI-1: 81.4 %) with MO during degradation process. Remarkably, the morphological changes of observed shapes before and after MO clearly show an effective performance, as was definite by the successful interfacial polymerization between membrane and POM/3-API. These help towards elimination of MO dyes at waste water sources, making the process environment-friendly.
