Diisopropanolamine (DIP A) with the mixture of other solvent, in aqueous solutions is frequently employed for removing carbon dioxide (C02) and hydrogen sulfide (HzS) from sour gas. Contamination oflarge amount of DIP A into wastewater stream occurs during turnaround activity where high pressure water jet is used to clean the inside of absorption and desorption columns. The DIP A is not readily biodegradable, thus such wastewater could not be treated via conventional treatment system. Heterogeneous photocatalytic degradation system has shown impressive performance in mineralization of various refractory organic pollutants. Semiconductor materials are employed as photocatalyst where the system involves simple setup at ambient condition. For present study, titanium dioxide (Ti02) photocatalyst were synthesized employing microemulsion method. The TiOz was modified with metal dopants (i.e Cu and/or Fe) to extend the light harvesting capacity of the photocatalyst in visible region.
