Abstract

The improvement of processes for maintaining our ecosystem amidst rapidly developing and sustaining pollution is the ever-growing demand. This current research work is aimed at developing useful nanomaterials, such as silica nanoparticles and graphene oxide nanoparticles from solid agro-waste, coconut husk. The nanoparticles obtained were then blended with two other polymers, namely polyhydroxyalkanotes, a microbial biopolymer and polyvinylpyrrolidone, a synthetic biodegradable polymer to form nanocomposites, which are used as the base for nanofiber fabrication through electrospinning. The nanocomposites were characterized through Fourier-transform infrared (FTIR) spectrometer and the nanofibers under scanning electron microscope. The nanofibers were subjected to analyze the ability to function as adsorbents. The composite nanofibers developed were able to remove 62% of methylene blue dye in the test solution in a span of 12 hours with additional benefits of easy removal of used adsorbents and adsorbates.
复合基静电纺纳米纤维吸附剂的制备及其在染料去除中的应用
在快速发展和持续污染的情况下,改善维持生态系统的过程是日益增长的需求。目前的研究工作旨在从固体农业废物椰子壳中开发有用的纳米材料,如二氧化硅纳米颗粒和氧化石墨烯纳米颗粒。然后将获得的纳米颗粒与另外两种聚合物混合,即聚羟基烷烃(一种微生物聚合物)和聚乙烯吡咯烷酮(一种合成的可生物降解聚合物),形成纳米复合材料,作为静电纺丝制备纳米纤维的基础。利用傅里叶变换红外光谱仪(FTIR)和扫描电镜对纳米复合材料进行了表征。研究了纳米纤维作为吸附剂的性能。开发的复合纳米纤维能够在12小时内去除测试溶液中62%的亚甲基蓝染料,并且易于去除使用过的吸附剂和吸附剂。
