Abstract: Cobalt tetra(N-carbonylacrylic) aminophthalocyanine was formed on the surface of cellulose fibers by graft copolymerization and a novel polymer catalyst,catalytic fibers(CoPcF) was thus obtained.The effects of pH and concentration of 2-mercaptoethanol on the catalytic oxidation activity of CoPcF towards oxidation 2-mercaptoethanol in aqueous solution were investigated.The experimental results demonstrated that the catalytic effect of CoPcF on of 2-mercaptoethanol is the best when pH=11,and it increases with the increasing of the concentration of 2-mercaptoethanol.Therefore,CoPcF has good catalytic oxidation activity on 2-mercaptoethanol at room temperature,and CoPcF is recyclable and it will not cause any secondary pollution.
