In this work, the removal of NOM (natural organic matter) as represented by humic acid by means of electrospun nanofiber adsorptive membranes (ENAMs) is described. Polyacrylonitrile (PAN) was used for the preparation of ENAMs incorporating silica nanoparticles as adsorbents. The addition of silica to the polymer left visible changes on the structural morphology and fibers' properties of the membrane. The membrane samples were characterized by pure water permeability, contact angle measurement, SEM, XPS, and XRD. This study assesses the preliminary performance of PAN-Si membranes for the removal of natural organic matter (NOM). The membrane rejected the humic acid, a surrogate of NOM, from 69.57% to 87.5%.
在这项工作中，描述了通过电纺纳米纤维吸附膜（ENAM）去除以腐殖酸为代表的天然有机物（NOM）的过程。聚丙烯腈（PAN）用于制备包含二氧化硅纳米颗粒作为吸附剂的ENAM。向聚合物中添加二氧化硅使膜的结构形态和纤维性能发生了明显变化。通过纯水渗透率、接触角测量、扫描电子显微镜（SEM）、X射线光电子能谱（XPS）和X射线衍射（XRD）对膜样品进行了表征。本研究评估了PAN-Si膜去除天然有机物（NOM）的初步性能。该膜对腐殖酸（NOM的替代物）的截留率为69.57%至87.5%。
