Visible light photosensitised cross-flow microfiltration membrane reactors for managing microplastic-contaminated bio-effluents. WATER RESEARCH 2025; 277:123317. [PMID: 40010124 DOI: 10.1016/j.watres.2025.123317] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/23/2024] [Revised: 02/15/2025] [Accepted: 02/17/2025] [Indexed: 02/28/2025]
Abstract
The demand for advanced water treatment solutions necessitates the development of multifunctional, photodynamically active membranes. Phthalocyanines (Pcs), a class of organic photosensitizers, offer significant potential for enhancing treatment efficacy through photodynamic activity. This study reports the development of Pc-modified polymeric microfiltration membranes as visible-light-responsive, multifunctional membrane reactors with enhanced photodynamic and filtration properties. Cobalt phthalocyanine (CoPc), zinc phthalocyanine (ZnPc), tetra-amino zinc phthalocyanine (TAZnPc), and tetra-sulfonated aluminum phthalocyanine (TSAlPc) were integrated into the membranes, imparting notable changes in morphology, surface wettability, and chemical functionality. Characterization revealed improvements in optical responsiveness and surface properties that contributed to robust photodynamic and filtration performance. Static photodynamic evaluations demonstrated high efficacy, with ZnPc mixed matrix membrane (MMM) achieving superior dye degradation and TSAlPc grafted membrane (GM) yielding significant bacterial inactivation. Filtration trials confirmed ZnPc MMM's biofouling resistance and permeance stability, reaching 99.97 % rejection of bio-fouled microplastics (MPs) and a 45 % permeance enhancement under irradiation. Virus filtration results demonstrated TSAlPc MMM's viral retention efficacy, achieving a 2.05-log reduction against Influenza A virus. These findings underscore the potential of Pc-functionalized membranes as promising candidates for advanced water treatment applications, offering robust contaminant rejection, biofouling control, and broad-spectrum antimicrobial efficacy in a single, multifunctional platform.

Abstract
Fumed silica was functionalized by piperazine followed by the reaction with 2- naphthalenesulfonyl chloride to prepare Fumed-Si-Pr-Piperazine-Naphthalenesulfonyl chloride (Fumed-Si-Pr-PNS), which was characterized to demonstrate the effective attachment on the surface of fumed silica. The optical sensing ability of Fumed-Si-Pr-PNS was studied via diverse metal ions in H2O solution by photoluminescence spectroscopy. The results showed that Fumed-Si-Pr-PNS detected selectively Hg2+ ions. The prepared sensor showed almost high absorption at different pH for Hg ion. After drawing various diagrams, The detection limits were calculated at about 12.45 × 10-6 M for Hg2+.

Utreja D. Sulfonamide functionalized silica nano-composite: characterization and fluorescence "turn-on" detection of Fe 3+ ions in aqueous samples. Photochem Photobiol Sci 2023:10.1007/s43630-023-00421-5. [PMID: 37186235 DOI: 10.1007/s43630-023-00421-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2022] [Accepted: 04/10/2023] [Indexed: 05/17/2023]
Abstract
We have synthesized novel sulfonamide-based nano-composite (SAN) for selective and sensitive detection of Fe3+ ions in aqueous samples. Morphological characterization of SAN was carried out with TGA, FT-IR, UV-Vis, ninhydrin assay, FE-SEM, pXRD, BET, EDX, and elemental analysis. The sensing nature, effect of pH, sensor concentration and response time analysis were accomplished with the help of emission spectral studies and SAN was assessed as "turn-on" emission detector for the biologically important Fe3+ ions. Here, the LOD and LOQ were computed to be 26.68 nM and 88.93 nM, respectively, and it was found to be much lower than the permissible limit of Fe3+ ions in drinking water. The accuracy of the sensor (SAN) was determined by testing the aqueous samples spiked with known concentrations of Fe3+ ions and results demonstrated 98.00-99.66% recovery, which made SAN a reliable, selective and sensitive chemosensor for the quantification of Fe3+ ions in fully aqueous media.

Abstract
We have synthesized sulfonamide based nano-composites of SiO2 and TiO2 for selective and sensitive determination of toxic metal ion Hg2+ in aqueous medium. Nano-composites (11) and (12) were morphologically characterized with FT-IR, solid state NMR, UV-vis, FE SEM, TEM, EDX, BET, pXRD and elemental analysis. The comparative sensing behavior, pH effect and sensor concentrations were carried out with fluorescence signaling on spectrofluorometer and nano-composites (11) and (12), both were evaluated as "turn-on" fluorescence detector for the toxic Hg2+ ions. The LODs were calculated to be 41.2 and 18.8 nM, respectively of nano-composites (11) and (12). The detection limit of TiO2 based nano-composites was found comparatively lower than the SiO2 based nano-composites.

Abstract
Porphyrins and related macrocycles have been studied broadly for their applications in medicine and materials because of their tunable physicochemical, optoelectronic and magnetic properties. In this review article, we focused on the applications of fluorinated porphyrinoids and their supramolecular systems and summarized the reports published on these chromophores in the past 5-6 years. The commercially available fluorinated porphyrinoids: meso-perfluorophenylporphyrin (TPPF20 ) perfluorophthalocyanine (PcF16 ) and meso-perfluorophenylcorrole (CorF15 ) have increased photo and oxidative stability due to the presence of fluoro groups. Because of their tunable properties and robustness toward oxidative damage these porphyrinoid-based chromophores continue to gain attention of researchers developing advanced functional materials for applications such as sensors, photonic devices, component for solar cells, biomedical imaging, theranostics and catalysts.
