In this study, polypropylene nonwoven was coated with chitosan after being activated by oxygen/argon low-pressure plasma. The chitosan-treated sample (PP-Ch) was coated with TiO nanoparticles by a pad-dry method. Silver nanoparticles were in situ synthesized on the chitosan-TiO-coated sample by a chemical reduction method. The morphology of each of the samples mentioned above was evaluated by FESEM. The efficiency of each sample in the removal of C.I. Acid Brown 248 from aqueous media was evaluated. The PP-Ch sample removed 90% of the dye at pH=3. Coating the PP-Ch sample with TiO and silver nanoparticles improved the dye removal efficiency under UV irradiation.
在本研究中，聚丙烯无纺布在经氧/氩低压等离子体活化后用壳聚糖进行涂层处理。经壳聚糖处理的样品（PP-Ch）通过浸轧干燥法用TiO纳米颗粒进行涂层。通过化学还原法在壳聚糖-TiO涂层样品上原位合成银纳米颗粒。通过场发射扫描电子显微镜（FESEM）评估上述各样品的形态。评估了每个样品从水介质中去除酸性棕248的效率。PP-Ch样品在pH = 3时去除了90%的染料。用TiO和银纳米颗粒对PP-Ch样品进行涂层提高了紫外辐照下的染料去除效率。
