Zusammenfassung: | Tris-(2,3-dibromopropyl) isocyanurate (TBC) is a brominated flame retardant, which has been found in several environmental and biological matrices in recent years. TBC has aroused high environmental concerns because of its bioaccumulation and biological toxicity. This work studied photodegradation of TBC for the first time. The optimal degradation conditions have been found that 95% of 10 μmol/LTBC was effectively decomposed after 120 min of UV radiation. UV lamp was found to be more effective than Xe lamp on the photodegradation. The degradation rate of TBC increased with increasing light intensity. Under UV illumination, the effect of pH on the photodegradation of TBC could be ignored and degradation reactions followed the pseudo-first-order kinetics. The addition of [Formula: see text] could not accelerate the degradation of TBC. The quenching experiments showed that TBC was directly photodegraded by UV illumination. These findings suggest that UV photodegradation is a potential method for the removal of TBC in aqueous solutions |
