A novel heterogoneous catalyst, viscose fiber.supported cobalt phthalocyanine (Co - TDTAPc - F), was prepared by immobilizing cobalt tetra(2,4- dichloro- 1,3,5 -triazine)aminophthalocyanine (Co - TDTAPc) on viscose fibers covalently. The oxidative removal of chloropheaols such as 2 - chlorophenol, 4 - chlorophenol, 2, 4 -dichlorophenol, and 2, 4, 6 - trichlorophenol was investigated in the catalytic oxidative system of Co TDTAPc- F/H2O2. Furthermore, more than 98% of these chiorophenols were decomposed in 4 h. Phenol, oxalic acid,maleic acid, and stlccinic acid, etc., were detected by high performance liquid chromatography (HPLC) and gas chromatography-mass speetrcphotometer (GC - MS), and these short-chain organic acids could be further oxidized easily. The results indicated that the catalytic oxidation in the Co - TDTAPc - F/H2O2 system leaded to a deeper oxidation. In addition, a degradation pathway for chlorophenols was proposed on the basis of detection of intermediate compounds.
