聚(甲基)丙烯酸酯/锰氧化物复合中空纤维制备及其催化氧化染料性能
Preparation of poly (meth) acrylate/manganese oxide composite hollow fiber and its catalytic performance for dye oxidation
摘要
Abstract
In order to achieve the purpose of separ ating manganese oxide from the treated water and reusing it, a hollow fiber based on the blend of poly (butyl methacrylate-co-hydroxyethyl methacrylate) and poly (butyl acrylateco-hydroxyethyl methacrylate) , which was prepared by wet spinning, was treated in potassium permanganate solutions that had different pH values under the condition of heating. Then the in-situ generated manganese oxide was loaded on the inner and outer surfaces of hollow fiber. Its morphology and surface elements were analyzed; additionally, its performance to catalyze H2O2 to oxidize cationic blue was also researched. The related results showed that the composite hollow fiber prepared in the potassium permanganate solution of a pH of 14.4 had the best catalytic activity among all the samples. At 90 min, the removal efficiency of cationic blue reached up to94.4％ in the presence of 0.5 mL H2O2, and when it was used for the second or third time, the removal efficiency of cationic blue was 79.3％ or 57.2％.关键词
