锦纶纤维负载钴酞菁催化氧化酸性红G的研究

Research on catalytic oxidation of Acid Red G using nylon fiber-supported Cobalt phthalocyanine

将可反应的水溶性钴酞菁(Co-TDTAPc)负载到锦纶纤维上制备了催化功能纤维(F-CoTDTAPc)。利用紫外/可见分光光度法对F-CoTDTAPc/H2O2体系催化氧化酸性红G进行研究,考察了氧化剂质量浓度、pH值、反应温度等对F-CoTDTAPc/H2O2体系氧化降解酸性红G的影响。结果表明,F-CoTDTAPc在H2O2存在下能快速催化氧化酸性红G,并具有较好的原位再生能力。气质联用分析结果表明,酸性红G分子已被氧化降解为可生物降解的脂肪酸类化合物,酸性红G在反应过程中发生了深度氧化降解。

This paper loads water-soluble reactive Cobalt phthalocyanine （Co-TDTAPc） to nylon fiber to prepare catalytic functional fiber （F-CoTDTAPc）. Besides, it uses ultraviolet/visible spectrophotometry methods to study the catalytic oxidation of Acid Red G in the presence of F-CoTDTAPc/ H2O2. Additionally, it also studies the impacts of the concentration of oxidant, pH and reaction temperature on oxidative degradation Acid Red G in F-CoTDTAPc/ H2O2 system. The results show that F-CoTDTAPc can effectively catalyze H2O2 to oxidize Acid Red G and can realize in situ regeneration. Furthermore, the results of gas chromatography/mass spectrometry indicate that the Acid Red G molecule has changed into biodegradable aliphatic acid compound by oxidative degradation and Acid Red G can deeply oxidize and degrade in the reaction process.
