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 viscose fibers covalently. The oxidative removal of chlorophenols 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 chlorophenols were decomposed in 4h. Phenol, oxalic aci... 相似文献

为提高传统共混工艺制备的阻燃粘胶纤维的耐水洗性,通过在阻燃粘胶液中加入自制硅烷偶联剂,间接地将纤维素和阻燃剂结合起来,减少水洗过程中阻燃剂的流失,考察了偶联剂用量、成膜温度及成膜时间对水洗后阻燃粘胶膜的极限氧指数(LOI)的影响.极限氧指数测试和能谱分析表明,硅烷偶联剂的适量加入有效减缓了阻燃粘胶膜LOI的下降. 相似文献
