Application of silica and germanium dioxide nanoparticles/ polyethersulfone blend membranes for removal of emerging micropollutants from water

This study fabricated silicon dioxide (silica) (SiO2) and germanium dioxide (GeO2) embedded polyethersulfone (PES) blend membranes using phase inversion method for the removal of EMPs from water samples collected from North West Province, South Africa. The EMPs were extracted and enriched by auto-trace solid-phase extraction and analyzed using comprehensive two dimensional gas chromatography coupled to time of flight mass spectrometry (GCxGC-TOFMS). The fabricated membranes' permeation properties were determined by computing the pure water flux and EMPs' rejection. The water flux was observed to increase with increase in transmembrane pressure as well as increase in SiO2 and GeO2 nanoparticle loadings in the polymer matrices. Compared to the pristine PES, the contact angles for the SiO2/PES and GeO2/PES membranes were much lower, showing increased hydrophilicity of the membranes with increase in SiO2 and GeO2 nanoparticle loadings in the matrices. The mean EMPs' concentrations (ng/L) ranges in the feed were found to be: BPA (5.19 ± 0.8 to 53.60 ± 4.25), CAF (6.09 ± 0.00 to 49.96 ± 3.45), CBZ (0.68 ± 0.00 to 3.06 ± 0.74), HHCB (21.31 ± 4.24 to 13.31 ± 14.8), AHTN (8.31 ± 2.23 to 141.82 ± 21.70), and NP (0–174.99 ± 14.5). Even though SiO2/PES membranes showed slightly higher EMPs' removal efficiencies than their GeO2/PES counterparts, both membranes sho...
