A more widespread use of conducting polymer nanostructures in environmental remediation is limited by their tendency to form agglomerates. In this study, we report the development of electrospun polystyrene/polyaniline composite membranes that can be used as efficient agents for the removal of dye molecules from aqueous solutions. These nonwoven polystyrene-polyaniline (NW PS-PANI) mats are formed after the incorporation of the conducting polymer into the surface of nonwoven polystyrene (NW PS) mats produced via the electrospinning method. The composite mats were characterized by contact angle measurements, SEM, FTIR and UV–vis spectroscopy. By performing experiments in batch mode, we examined the capacity of these mats for removing Congo red (CR) molecules, a prototypical azo dye, as a function of pH, interaction time and dye initial concentration. These membranes are hydrophilic and have a large CR removal efficiency. The zero point charge pH of the NW PS-PANI membranes was determined as 6.4, and we have found that their adsorption capacity reaches a maximum of 380.0 mg/g at pH 6.0. An easy recovery of the contaminant is possible by using these mats, which can be reutilized in at least 13 consecutive adsorption/desorption cycles, without significant losses in their adsorption capacity. In addition, they can be adapted for usage in compact filtration systems for an even faster removal of the dissolved dye molecules.

导电聚合物纳米结构在环境修复中的更广泛使用受到其形成附聚物趋势的限制。在这项研究中，我们报告了电纺聚苯乙烯/聚苯胺复合膜的发展，该膜可用作从水溶液中去除染料分子的有效试剂。这些非织造聚苯乙烯-聚苯胺（NW PS-PANI）毡是在将导电聚合物掺入通过以下方法生产的非织造聚苯乙烯（NW PS）毡的表面后形成的电纺方法。通过接触角测量，SEM，FTIR和UV-vis光谱对复合毡进行了表征。通过以批处理模式进行实验，我们检查了这些毡垫用于去除刚果红（CR）分子（一种典型的偶氮染料）的能力，它是pH，相互作用时间和染料初始浓度的函数。这些膜是亲水的并且具有大的CR去除效率。NW PS-PANI膜的零点电荷pH值确定为6.4，我们发现它们的吸附容量在pH 6.0时最大达到380.0 mg / g。通过使用这些垫，可以轻松回收污染物，这些垫可以在至少13个连续的吸附/解吸循环中重新使用，而不会显着降低其吸附能力。此外，
