| 摘 要： | 以医用纱布(medical gauze，MG)同时作为模板和还原剂，通过原位氧化还原反应，简便地制备了MG负载的MnO2纳米颗粒(MnO2 NPs/MG)，并对其形貌、成分进行表征。结果表明，MnO2 NPs均匀地分散于MG纤维表面。结合MnO2纳米材料的吸附性能和MG复合材料的操作便捷性，将MnO2 NPs/MG进一步应用于亚甲蓝染料的去除。结果表明，在中性条件下，通过简单的浸泡搅拌，MnO2 NPs/MG对亚甲蓝的去除率可达85.09%，并且可以通过增大吸附材料用量与染料初始浓度的比例提高去除率。等温吸附和动力学研究证明，MnO2 NPs/MG对亚甲蓝的吸附符合Langmuir吸附等温模型和拟二级动力学模型。

| Abstract: | Using medical gauze (MG) as both template and reductant, MG templated manganese dioxide nanoparticle (MnO2 NPs/MG) was facilely synthesized through an in situ redox reaction. The morphology and composition were characterized. MnO2 NPs were evenly loaded and dispersed on the surface of MG fibers. Combing the adsorption property of MnO2 NPs with ease of operation of MG, MnO2 NPs/MG were further applied to the removal of methylene blue. The results indicated that, by simple soaking and stirring under neutral conditions, the removal efficiency can reach 85.09%, and it can be improved by increasing the ratio of adsorption material dosage to the initial amount of dye. Through isothermal adsorption and kinetic studies, it was proved that the adsorption of methylene blue by MnO2 NPs/MG conformed to Langmuir adsorption isothermal model and pseudo-second-order kinetic model. |
