| 摘要:本研究通过缩聚反应制备端氨基聚酰胺多胺(PPC),将PPC与二氧化钛(TiO₂)进行配位络合后,采用浸渍法处理纯活性炭纸,成功制备出PPC/TiO₂负载活性炭纸,并系统探究了其甲醛去除性能。结果表明,纯TiO₂颗粒极易发生团聚现象,粒径集中在5 058 nm左右,经PPC复合改性后,TiO₂颗粒粒径显著降至27 nm左右,团聚问题得到有效改善;负载活性炭纸可通过物理吸附、化学吸附与光催化降解的协同作用实现甲醛的高效去除,在300 W镇流高压汞灯照射条件下,表现出快速、高效且可循环的甲醛净化性能:当PPC/TiO₂负载量为20 g/m²时,该负载活性炭纸在30 min内的甲醛去除率可达40%,饱和去除率高达95.7%,且其循环再生性能优异,经过5次光催化循环测试后,饱和去除率仍可保持在90.8%。此外,与活性炭纸原纸相比,该负载活性炭纸的透气量基本保持不变,抗张指数提升20.4%,兼具良好的透气性与较高的力学强度,具备实际应用潜力。 |
| Abstract:In this study, amino-terminated polyamide polyamine (PPC) was prepared via polycondensation reaction. After coordination reaction with titanium dioxide (TiO₂), activated carbon paper was treated by impregnation method to successfully prepare PPC/TiO₂-loaded activated carbon paper, and its formaldehyde removal performance was systematically investigated. The results showed that pure TiO₂ particles were prone to agglomeration, with particle sizes concentrated around 5 058 nm. After composite modification with PPC, the particle size of TiO₂ particles was significantly reduced to about 27 nm, and the agglomeration problem was effectively alleviated. The loaded activated carbon paper could achieve efficient formaldehyde removal through the synergistic effect of physical adsorption, chemical adsorption and photocatalytic degradation. Under the irradiation of a 300 W ballast high-pressure mercury lamp, it exhibited rapid, efficient and recyclable formaldehyde purification performance: when the loading amount of PPC/TiO₂ was 20 g/m², the formaldehyde removal rate of the loaded activated carbon paper reached 40% within 30 min, and the saturated removal rate was as high as 95.7%. In addition, it had excellent cyclic regeneration performance, and the saturated formaldehyde removal rate could still be maintained at 90.8% after 5 photocatalytic cycles. Furthermore, compared with pure activated carbon paper, the air permeability of the loaded activated carbon paper remained basically unchanged, and the tensile index was increased by 17%, which had both good air permeability and high mechanical strength, showing potential for practical application. |
