摘要

The utilization of agricultural waste as a derivative biomass material for developing membrane-based filtration have several ecofriendly environmental solutions. In this study, silica nanoparticles, derived from wheat husk as agriculture waste recycling, were compared with commercial silica nanoparticles for nanocomposite membrane synthesis. The developed membranes were fabricated using electrospinning techniques to produce nanocomposite fibers followed by postprocess treatment to improve surface wettability using 0.1 M NaOH solution. Several materials characterizations and membrane permeation of water evaluation were performed. These characterizations include morphology, fiber distribution, water flux, and other properties of nanocomposite membranes. The results of XRD diffraction of the obtained husk-derived SiO2 nanoparticles confirmed the semi-crystalline nature. Moreover, morphological characterization using FE-SEM indicated smaller membrane diameters when utilizing wheat husk (WH) derived SiO2 nanoparticles and improved water flux of 3.07 m3.m− 2.hr− 1. Furthermore, membranes incorporating WH derived SiO2 nanoparticles exhibited improved water contact angles reached to 44o ± 3o and total dissolved solids (TDS) rejection compared to membranes with commercial counterparts (from 8.22 to 8.65% after treatment). Overall, the WH recycling produces SiO2 NPs that can be used for developing nanocomposite membrane with improved results comparing to its commercial counterpart. Overall, the treatment of the developed membranes with 0.1 M NaOH enhanced water flux while maintaining a homogeneous fiber structure with hydrophilic properties.
