Abstract


In this paper, the activity of TiO2–P25 in the photodecomposition of recalcitrant organic compounds such as n–lauryl diethanolamine (n–LDA) and cinnamic acid (CA) solution in UV + BLED light in presence of oxygen was investigated and the optimum conditions of reaction were determined. With physicochemical characteristics such as anatase/rutile ratio of 80/20, the crystallite size of 23 nm, BET surface area of 43.6, the light absorption wavelength of 390 nm, band gap energy of 3.17 eV, and point of zero charge of 6.3, TiO2–P25 catalyst is able to photodecompose more than 95 % of LDA and CA after 90 minutes in presence of oxygen under irradiation of UV–B light.


Keywords
