Photocatalytic activity of different photocatalysts for mineralization of DFTA is compared under solar and UV irradiation for COD removal (with initial COD of 75,000 mg/L) has been carried out. Kinetics for Ag-Fe codoped TiO2 photocatalysis has been determined. The photocatalysts can be easily separated from the water after application and show good stability up to 4 runs indicated from six recycled tests. }, number = {68}, doi = {10.12944/CWE.15.1.17} }
