Laboratory scale water circuit including a photocatalytic reactor and a portable in-stream sensor to monitor pollutant degradation
We describe a lab-scale closed-circulating test system for photocatalytic wastewater treatment. The system comprises a UV-LED photoreactor, a microcirculating fluid pump, and an in-stream sensor unit. The reactor can hold volumes up to 250 mL and is optimized to study the degradation of pollutant concentrations in the microgram to milligram per liter range using photocatalysts fixed to a planar surface ...

Synthesis, characterization and photocatalysis enhancement of Eu2O3-ZnO mixed oxide nanoparticles
Pure ZnO nanoparticles (NPs) and mixed Eu2O3 and ZnO NPs with different Eu2O3 ratios (5%, 10%, and 15%) were synthesized by a precipitation method under optimum conditions. The synthesized samples were characterized by means of X-ray diffraction, scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy, transmission electron microscopy (TEM), Fourier transform infrared (FTIR) spectroscopy, Raman spectroscopy, and UV–vis diffuse reflectance spectroscopy. ...
