"Alkanolamine is widely applied in industry usually for gas treatment process to remove acid gases prior to utilization. Though the absorbent is recycled through the system, some carry over into water stream is unavoidable. Due to high solubility and toxicity of the absorbent, simple removal process or conventional wastewater treatments are inefficient to treat the contaminated water. The photocatalytic degradation of organic compounds were reported to be efficient for treatment or persistent pollutant. In this paper, the synthesized TiO2 was modified with Cu, Fe or Cu-Fe via wet impregnation method. Characterization of the prepared photocatalysts were conducted using BET analyzer, X-ray diffractometer, transmission electron microscope, diffuse reflectance UV-Vis spectrophotometer, and point of zero charge determination. The band gap of the photocatalysts was reduced to as low as 2.55 eV (1.8Cu-0.2Fe/TiO2) compared to bare TiO2 with a band gap of 3.11 eV. The performance of the photocatalysts for photodegradation of diisopropanolamine (DIPA) was studied using a batch glass reactor under simulated sunlight. The bimetallic photocatalyst 1.8Cu-0.2Fe/TiO2 displayed the highest chemical oxygen demand (COD) and DIPA removals of 67 and 92, respectively. Based on the photocatalytic degradation data, all the photocatalysts were found to follow pseudo-first order kinetic with 1.8Cu-0.2Fe/TiO2 giving the highest apparent rate constant, kapp = 16.5�10-3 min-1. © 2016 The Authors.
