| Abstract | Removal of protein from artificial and natural wastewater was performed using Fe-doped TiO2 film under visible lightin an in-house made photoreactor. The Fe(III) dopant improved TiO2 absorption in the visible region. Fe(III) dopant at 2.5%wt.in TiO2 gave the highest yield of protein photodegradation. Further increase in the dopant concentration decreasedphotoefficiency due to a higher electron-hole recombination rate and a reduced light harvesting capability. The conditions wereoptimal for protein remediation in an alkaline medium with 10%v/v H2O2. The degradation of protein started with oxidation ofamino acids, which were further broken down to carbon skeletons and ammonium ions. The carbon skeletons and ammoniumions were oxidized to carbon dioxide and nitrates, respectively. The results obtained may help understand the phytotoxicity ofnanomaterials interacting in the environment, prior to their use in agriculture. |
