摘要:
以CTAB为模板, TEOS为硅源, P25和Fe3O4纳米颗粒为功能性纳米颗粒, 通过水热法一步制备出具有可回收性、光降解性和高吸附效率的介孔染料吸附材料.结果表明: 所制备的材料对染料的吸附效果很好，吸附率可达99.0%; 在光照下, 染料可以在10 min内迅速降解; 在磁场作用下, 材料得以回收, 并且经焙烧处理后可以重复利用；材料在重复利用5次后，吸附率为59.4%，染料在60min内可以完全降解，符合工业染料废水处理剂的要求.
Abstract:
Mesoporous adsorbing materials for dye with recyclability, photodegradability and high adsorbing efficiency was prepared through the hydrothermal method, using CTAB as the templating agent and TEOS as silica source, P25 and Fe3O4 nanoparticles as the functional nanoparticles. The results show that prepared materials have good adsorption rate of 99.0% for dyes. The dyes can be degraded within 10mins under the light radiation by the materials. The materials can be recycled under magnetic effect and reused after being calcined. The materials still show good adsorbing rate of 59.4% for dye and can photodegrade the dyes completely within 60mins after reusing five times, which meets the needs of industrial waste water treatment.
