In addition, a stepwise degradation of TCP, beginning with the formation of a major product 2,6-dichloro-1,4-benzenediol via substitution, is proposed through a detailed analysis of gas chromatography/mass spectrometry.展开更多

Dyes in wastewater from a textile factory can be effectively degraded by photo-catalysis with TiO 2 and ultraviolet light or sunshine, but the reaction rate could be slowed down if copper or zinc salt exists in the solution.展开更多
