用于污水处理的纤维素纳米颗粒表面改性实验研究

纤维素纳米颗粒是一种容易制备,且价格低廉并具有一定可再生性的吸附材料,被广泛运用到有机污染物的去除等方面.通过实验制备高纯度纤维素纳米材料,并将其与3种不同的脂肪酸进行反应,得到改性后的纤维素纳米材料.结果表明：改性后材料的碳元素含量大幅提升,长碳链被成功移植到纤维素纳米材料的表面;通过FTIR,XPS和XRD光谱分析表明,所生成的化合物与理论分析结果相符.该改性纤维素纳米材料的研究成果将为变电站及火电厂提供更先进的污水处理材料.

Cellulose Nanoparticles Surface Modification Experiments for Sewage Treatment

Cellulose nanoparticles is one kind of adsorption material,which is of low price and reproducibility and easy to prepare,so it is widely used to remove organic pollutants and other aspects.This paper prepares the high-purity cellulose nano-materials through experiment,making the nano-materials reacting with three kinds of different fatty acids to obtain modified cellulose nanomaterials.The results show that the carbon content of the material increased dramatically after the modification,and long carbon chain have been successfully transplanted to the surface of the cellulose nano-materials.Moreover,the paper finds out the compound came from the experiment is in good agreement with the theoretical analysis results by using FTIR,XPS and XRD analysis.The researches results above will provide more advanced materials for the sewage treatment to substation and thermal power plant.
