摘要

利用氯化胆碱和乙二醇(CC:EG)以 1:1 的比例组成的深共晶溶剂(DES)系统作为绿色模板,提出了一种废弃/废弃聚砜(WPSF)膜升级再循环的简便途径。这种方法为解决聚合物膜废物管理难题提供了可行的解决方案,同时还促进了方法的可行性、资源效率和经济可行性。在 200 °C 溶剂热转化和 900 °C 高温分解之前,WPSF 掺杂了锰离子。所获得的功能性多孔碳对孔雀石绿(MG)(423.72 mg/g)、络氨黑-T(EBT)(326.79 mg/g)、双氯芬酸(DCF)(195.31 mg/g)和氧氟沙星(OFX)(121.8 mg/g)具有卓越的吸附能力。吸附过程遵循假二阶动力学,与 Langmuir 等温线完全吻合。此外,经过优化的碳材料(即 Mn-WPSF-01)被用作基于吸附的膜过滤系统,不同进料流的水通量均达到 965 L.m-2.h-1,即使经过十次再生循环,也能获得 90% 的出色滤除率。因此,掺锰碳材料集制备简便、坚固耐用、吸附性能高以及可回收性好等优点于一身。此外,利用热解后的碳材料或二次碳材料作为超级电容器的电极系统,在电流密度为 0.1 A/g 时,比电容为 110.88 F/g,在电流密度增加到 5 A/g 时,循环约 20,000 次,容量保持率为 90.85%。因此,这种方法有望回收利用 WPSF,通过更环保的方式将其应用于水处理和能源领域。

Upcycling waste polymer membranes through eco-friendly solvent-catalysed valorisation for energy and environmental solutions

A facile pathway of upcycling waste/discarded polysulfone (WPSF) membranes has been proposed using deep eutectic solvent (DES) system composed of choline chloride and ethylene glycol (CC:EG) in 1:1 ratio as a green template. This approach offers a viable solution for addressing polymer membrane waste management challenges while simultaneously promoting feasible method, resource efficiency and economic viability. The WPSF was doped with Mn ions prior to the solvothermal conversion at 200 °C and pyrolysis at 900 °C. The obtained functional porous carbon showed superior adsorption capacity towards Malachite green (MG) (423.72 mg/g), Eriochrome black-T (EBT) (326.79 mg/g), Diclofenac (DCF) (195.31 mg/g), and Ofloxacin (OFX) (121.8 mg/g). The adsorption followed pseudo second order kinetics and well agreed with Langmuir isotherm. Further, the optimised carbon material i.e., Mn-WPSF-01 was used as an adsorptive-based membrane water filtration system, in which a remarkable water flux about 965 L.m−2.h−1 for different feed streams with outstanding rejection of >90% even after ten cycles of regeneration was obtained. Therefore, Mn-doped carbon materials integrate the advantages of easy preparation, robustness, and effective adsorption performances, as well as good recyclability. Furthermore, the utilized or secondary carbon materials were used as electrode system in supercapacitors after the pyrolysis, where they displayed a specific capacitance of 110.88 F/g at 0.1 A/g of current density with capacity retention 90.85% for about 20,000 cycles with a current density increased to 5 A/g. Therefore, this approach promises to recycle the WPSF via potential applications in water treatment and energy applications through greener way.
