Continuous process applied to degradation of triclosan and 2.8-dichlorodibenzene-p-dioxin

This study describes the use of a prototype for the continuous photocatalytic reaction process using Fe/Nb 2 O 5 -immobilized catalyst for triclosan and 2.8-dichlorodibenzene-p-dioxin (2.8-DCDD)’s degradation. The experiments were carried out with different parameters and matrices in a steady state....

Description
Summary:This study describes the use of a prototype for the continuous photocatalytic reaction process using Fe/Nb 2 O 5 -immobilized catalyst for triclosan and 2.8-dichlorodibenzene-p-dioxin (2.8-DCDD)’s degradation. The experiments were carried out with different parameters and matrices in a steady state. In addition, photolysis and photocatalytic tests were performed. The results indicated that the generation of 2.8-DCDD was observed in matrices with Cl − . The Fe/Nb 2 O 5 -immobilized catalysts were efficient in the degradation of triclosan and 2.8-dichlorodibenzene-p-dioxin. However, 2.8-DCDD formation was not observed in the ultra-pure water matrix, which indicated influence of ions. The photocatalysis was more efficient than the photolysis when comparing both matrices and radiation. Even with a radiation oscillation, the solar process showed positive results.
