Photocatalytic Adsorbent for the Removal of MicroPollution from Industrial WWTPs

Recently, concern about emerging contaminants such as micro-pollutant including pharmaceuticals and perfluorinated compounds has increased extensivel.Eliminating these substances from wastewater is complicated, and conventional treatment methods are not suitable for removing micro-pollutant.This study investigated a heterogeneous photocatalytic degradation process to remove micro-pollutants from aqueous solutions.As a photocatalytic adsorbent, Fe/Mn-SiO2 nanocomposites and Fe-AC were prepared to remove pharmaceuticals and perfluorinated compounds.In addition, process parameter optimization (catalyst dosage, UV power intensity, pH, H2O2) has been investigated.Spectroscopic and microscopic properties of the catalysts were analysed with BET, SEM, TEM, EDS, XRD, XPS, etc.Moreover, the reusability of photocatalytic adsorbents, and the field applicability in actual waste water was studied.According to this research, Fe/Mn-SiO2 and Fe-AC can be a practical approach for the treatment of micro-pollutants such as pharmaceuticals and perfluorinated compounds in aqueous environments.
