This research aims to investigate the possibility of electrospun fibers from Polymers of Intrinsic Microporosity (PIM-1) as an alternative adsorbent for aniline removal from both air and aqueous solution. Adsorption properties of electrospun PIM-1 fibers were compared with powder and film form of PIM-1. While electrospun PIM-1 nanofibrous mat can adsorb 871 mg g aniline from air, it can also adsorb 78 ± 5.4 mg g aniline from aqueous environment when 50 mg L aniline solution is used. The experimental maximum adsorption capacity of electrospun PIM-1 fibers was found as (q) 138 mg g. Langmuir and Freundlich isotherm models have been studied and Langmuir model found more appropriate for aniline adsorption on electrospun PIM-1 fibers. The study reveals that self-standing electrospun fibrous mat of PIM-1 has shown potential to be used as an efficient adsorbent material for the adsorption of VOCs from air and aqueous system thanks to its fast kinetic and high adsorption capacity.
本研究旨在探讨将聚合物固有微孔（PIM-1）制成电纺纤维作为替代吸附剂，从空气和水溶液中去除苯胺的可能性。比较了电纺 PIM-1 纤维与 PIM-1 的粉末和薄膜形式的吸附性能。电纺 PIM-1 纳米纤维垫可以从空气中吸附 871mg/g 的苯胺，而当使用 50mg/L 的苯胺溶液时，它也可以从水溶液中吸附 78±5.4mg/g 的苯胺。实验得到的电纺 PIM-1 纤维的最大吸附容量为（q）138mg/g。研究了 Langmuir 和 Freundlich 等温模型，发现 Langmuir 模型更适合于电纺 PIM-1 纤维对苯胺的吸附。研究表明，由于其快速动力学和高吸附容量，自支撑的电纺 PIM-1 纤维垫有望成为从空气和水系统中吸附 VOCs 的高效吸附材料。
