摘要
为提高负载型催化剂对室内甲醛(HCHO)等有害气体的催化降解性能,以氨基改性聚乙烯醇缩丁醛(mPVB)为载体,聚甲基丙烯酸(PMAA)为模板,负载氧化锰(MnO_(x)),制备一种新型MnO_(x)/mPVB多孔纤维膜,并研究其在室温下对连续释放的低浓度甲醛的去除性能。结果表明:2%(质量分数)的MnO_(x)/mPVB多孔纤维膜对甲醛的去除性能最佳,去除率为88.8%,且多次循环实验后仍保持在80%以上。
To improve the catalytic degradation performance of supported catalysts for indoor formaldehyde(HCHO)and other harmful gases,a novel MnO_(x)/mPVB porous fiber membrane was prepared using amino-modified polyvinyl butyral(mPVB)as support,polymethacrylic acid(PMAA)as templates to support manganese oxide(MnO_(x)),and the removal performance of continuously released low-concentration formaldehyde at room temperature was also investigated.The results showed that the 2%(Mass fraction)MnO_(x)/mPVB porous fiber membrane had the best removal performance for HCHO,with a removal rate of 88.8%,and it remained above 80%after multiple cycle experiments.
