Abstract

Abstract Results of the photodegradation of 3,4-DPA in the presence of TiO 2 are discussed. 100% destruction of an aqueous solution of 3,4-DPA (265 ppm) occurred within 5 h when illuminated with a medium pressure lamp ( λ ≈ 365 nm) in the presence of TiO 2. During the photodegradation of 3,4-DPA, formation of Cl −, H +, NO 3 − and CO 2 were observed. Application of solar energy instead of artificial illumination also gave successful results.
