Concurrent photocatalytic degradation of organic contaminants and photocathodic protection of steel Ag–TiO2 composites
Liang, Robert; Schneider, Olivia M.; Lun, Nathan; Enrique, Pablo D.; Saha, Dulal C.; Li Chun Fong, Lena C. M.; Jaciw-Zurakowsky, Ivana; Servos, Mark R.; Peng, Peng; Zhou, Norman Y. (Elsevier, 2018-11-01)In this study, coupled titanium dioxide-silver composite and steel electrode pairs were investigated for their use in cathodic protection under illuminated and dark conditions to prevent corrosion and enhance contaminant ... -
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 ... -
Nanomaterials in Water Remediation: Functionalization and Applications for Pharmaceutical Removal in Municipal Wastewater Effluent
Jaciw-Zurakowsky, Ivana (University of Waterloo, 2019-09-10)With an increasing population, there is a higher pressure on natural resources including water. Increased water consumption, altered hydrology and pollution, threaten the sustainability of aquatic ecosystems and water ... -
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 ...
