Characterization of Photocatalyst for Degradation of Diisopropanolamine (DIPA) Using Photo-Fenton

Alkanolamines such as diisopropanolamine (DIPA) are used to treat natural gas in order to remove the acid gases, such as carbon dioxide, CO2 and hydrogen sulfide, H2S in it. The wastewater of this process contained high amount of the amines in which causes the COD reading to be high. Therefore, methods of degrading the recalcitrant pollutant were introduced using photo-Fenton reaction, in which Fe catalysts is added into the wastewater and the reaction took place under the illumination of light. The wastewater undergo oxidation process producing •OH radical which later will react with the amines and degrade them. Focusing on one method to synthesize the catalysts, few catalysts were developed to help in the degradation process of DIPA. The catalysts are characterized and tested in the wastewater in the presence of UV and visible light. The catalysts are characterized in order to obtain the suitable catalysts that will give higher DIPA degradation in the wastewater.
