Abstract
Oil spill pollution poses severe risks to water resources, causing significant harm to marine ecosystems and presenting an ongoing threat to environmental health. To address this issue, various oil sorbent materials have been researched and evaluated for their effectiveness in mitigating such pollution. In this study, we successfully fabricated a highly efficient hydrophobic nanofibrous membrane using 4,4′-(hexafluoroisopropylidene) diphthalic anhydride (6FDA)-based semi-alicyclic polyimide through electrospinning technology. The resulting membrane exhibits a uniform nanofibrous structure with a bead-free surface morphology. Contact angle measurements of approximately 133° confirmed the membrane's hydrophobicity, a critical property for effective oil sorption. Oil uptake tests demonstrated exceptional performance, with the sorbent showing a high adsorption capacity of 78, 50 and 45 g g−1 for crude oil, diesel, and kerosene, respectively. Given its rapid adsorption rate and robust performance, this polyimide-based nanofibrous membrane is a promising material for sustainable oil spill cleanup applications.
溢油污染对水资源构成严重风险，对海洋生态系统造成重大损害，并对环境健康构成持续威胁。为了解决这一问题，人们对各种吸油材料进行了研究，并对其减轻污染的有效性进行了评估。本研究以4,4′-（六氟异丙基）二苯二酸酐（6FDA）为原料，采用静电纺丝技术制备了高效疏水纳米纤维膜。所得膜具有均匀的纳米纤维结构和无珠的表面形貌。约133°的接触角测量证实了膜的疏水性，这是有效吸油的关键特性。吸油测试显示出优异的性能，吸附剂对原油、柴油和煤油的吸附量分别为78、50和45 g g−1。由于其快速的吸附速率和坚固的性能，这种聚酰亚胺基纳米纤维膜是一种很有前途的可持续溢油清理材料。
期刊介绍：
The Journal of Water Process Engineering aims to publish refereed, high-quality research papers with significant novelty and impact in all areas of the engineering of water and wastewater processing . Papers on advanced and novel treatment processes and technologies are particularly welcome. The Journal considers papers in areas such as nanotechnology and biotechnology applications in water, novel oxidation and separation processes, membrane processes (except those for desalination) , catalytic processes for the removal of water contaminants, sustainable processes, water reuse and recycling, water use and wastewater minimization, integrated/hybrid technology, process modeling of water treatment and novel treatment processes. Submissions on the subject of adsorbents, including standard measurements of adsorption kinetics and equilibrium will only be considered if there is a genuine case for novelty and contribution, for example highly novel, sustainable adsorbents and their use: papers on activated carbon-type materials derived from natural matter, or surfactant-modified clays and related minerals, would not fulfil this criterion. The Journal particularly welcomes contributions involving environmentally, economically and socially sustainable technology for water treatment, including those which are energy-efficient, with minimal or no chemical consumption, and capable of water recycling and reuse that minimizes the direct disposal of wastewater to the aquatic environment. Papers that describe novel ideas for solving issues related to water quality and availability are also welcome, as are those that show the transfer of techniques from other disciplines. The Journal will consider papers dealing with processes for various water matrices including drinking water (except desalination), domestic, urban and industrial wastewaters, in addition to their residues. It is expected that the journal will be of particular relevance to chemical and process engineers working in the field. The Journal welcomes Full Text papers, Short Communications, State-of-the-Art Reviews and Letters to Editors and Case Studies
