Oxidative Removal of Chlorophenols Using Fiber-supported Cobalt Phthalocyanine
A novel heterogeneous 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 the viscose fiber by the formation of a covalent bond.The oxidative removal of chlorophenols such as 2-chlorophenol,4-chlorophenol,2,4-dichlorophenol and 2,4,6-trichlorophenol in the catalytic oxidative system of Co-TDTAPc-F/H2O2 was investigated.Furthermore,more than 98％ of 2-chlorophenol was decomposed in 4 hours.HPLC and GC-MS results indicate that the main intermediates in 2h were phenol and oxalic acid,maleic acid and succinic acid,etc.Compared with other methods,these short-chain organic acids can be effectively degraded in the catalytic oxidation system.The results indicate that the catalytic oxidation in the Co-TDTAPc-F/H2O2 system leads to a deeper oxidation.In addition,a degradation pathway for chlorophenols is proposed on the basis of detection of intermediate compounds.
