Abstract:

In this study, ZnO/Zeolite Y composites were synthesized by the SSD method and were employed, in order to investigate their photocatalytic performance, in NH4+/NH3 removal from the aqueous solution. FT-IR spectroscopy, UV-VIS spectroscopy, SEM and EDX analyses were applied to characterize these composites. A set of experiments was conducted under conditions such as solution pH (3-11), ZnO loading (10-50 wt%) and pollutant concentration (25-315 mg/L). About 65% of NH4+/NH3 removal percentage was achieved at optimal conditions (pH (11), ZnO loading (30 wt%) and NH4+/NH3 concentration (170 mg/L)).
