摘要
利用接枝反应将马来酸酐改性氨基钴酞菁(CoPc)负载到纤维素纤维上,制得新型催化纤维(CoPcF)。考察了水溶液中pH值、巯基乙醇浓度对CoPcF催化性能的影响。结果表明:在pH值为11时,CoPcF对巯基乙醇的催化活性最高;随着巯基乙醇浓度的增加,CoPcF对巯基乙醇的催化活性也不断增加。因此,CoPcF在室温下对巯基乙醇具有良好的催化氧化活性,能重复使用且对环境无二次污染。
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-mereaptoethanol 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.
