纤维素纤维负载钴酞菁对活性染料X-3B的降解

Degradation of Reactive Dye X-3B Dye by CoPc Loaded with Cellulose Fiber

利用纤维素纤维通过共价键负载氨基钴酞菁,制备出具有催化功能的纤维素纤维(CoTDTAPc-F)。选择活性染料X-3B为模型底物,环境友好的双氧水为氧化剂。研究表明十二烷基苯磺酸钠(SDBS)的SO-3的"Push"效应对CoTDTAPc-F/H2O2催化体系具有促进作用。此外探索了pH,H2O2初始浓度、温度等对催化体系的影响。结果表明:一定量的SDBS能够有效地促进CoTDTAPc-F/H2O2体系催化氧化降解染料的效率,在中性到碱性pH范围内,升高温度和增加H2O2都能够有效提高催化活性;无机盐NaCl的加入对催化活性没有影响;此外催化剂多次循环使用后其活性没有明显下降。

CoTDTAPc-F with catalytic function was prepared by use of cellulose fiber loaded onto cobalt phthalocyanine（CoPc）via covalent bond.Reactive dye X-3B was chosen as model substrate,and hydrogen peroxide was chosen as the oxidizing agent.The researches indicate that＂Push＂effect of SO-3of sodium dodecyl benzene sulfonate（SDBS）can promote CoTDTAPc-F/H2O2 catalytic system.Furthermore,the effects of pH,concentration of H2O2 and temperature et al.on catalytic system were also studied.The results indicate that certain amount of SDBS can effectively promote oxydative degradation efficiency of CoTDTAPc-F/H2O2 catalytic system;from pH 7to 11,temperature rise and the rise in H2O2 can effectively boost catalytic activity.The addition of inorganic salt（NaCl）has no effect on catalytic activity.Besides,activity of the catalyst does not obviously decline after recycling.
