Development and Evaluation of Ag-TiO2 Nano-photocatalysts for the removal of natural organic matter and pharmaceuticals
Fattahi, Azar (University of Waterloo, 2020-01-08)Increasing the population and growing industries lead to contamination of surface and groundwater and threaten the sustainability of aquatic ecosystems and water resources. Some of the main contributors to water pollution ... -
Effect of Background Water Matrices on Pharmaceutical and Personal Care Product Removal by UV-LED/TiO2
Fattahi, Azar; Jaciw-Zurakowsky, Ivana; Srikanthan, Nivetha; Bragg, Leslie M.; Liang, Robert; Zhou, Norman Y.; Servos, Mark. R.; Arlos, Maricor Jane (Multidisciplinary Digital Publishing Institute, 2021-04-30)In this study, we evaluated the effectiveness of UV-LED-irradiated TiO2 in removing 24 commonly detected PPCPs in two water matrices (municipal wastewater effluent and Suwannee River NOM–synthetic water) and compared their ... -
Photocatalytic Degradation of Microcystins by TiO2 Using UV-LED Controlled Periodic Illumination
Schneider, Olivia M.; Liang, Robert; Bragg, Leslie M.; Jaciw-Zurakowsky, Ivana; Fattahi, Azar; Rathod, Shasvat; Peng, Peng; Servos, Mark. R.; Zhou, Norman Y. (Multidisciplinary Digital Publishing Institute, 2019-02-14)Toxic microcystins (MCs) produced by freshwater cyanobacteria such as Microcystis aeruginosa are of concern because of their negative health and economic impacts globally. An advanced oxidation process using UV/TiO2 offers ... -
Utilizing UV-LED pulse width modulation on TiO2 advanced oxidation processes to enhance the decomposition efficiency of pharmaceutical micropollutants
Liang, Robert; Van Leuwen, Jocelyn C.; Bragg, Leslie M.; Arlos, Maricor; Li Chun Fong, Lena C. M.; Schneider, Olivia M.; Jaciw-Zurakowsky, Ivana; Fattahi, Azar; Rathod, Shasvat; Peng, Peng; Servos, Mark R.; Zhou, Norman Y. (Elsevier, 2019-04-01)The presence of pharmaceutical and personal care products (PPCPs) in aquatic systems has been a growing cause for concern. Advanced oxidation processes such as UV/TiO2 (ultraviolet light/titanium dioxide) can break down ...
