The present study focuses on the fabrication of polysulfone (PSf)-clay minerals impregnated hybrid membrane for treatment of Cu (II) ions. Blending and phase inversion methods have been employed to develop clay-based membranes by the mixing of bentonite, sepiolite and zeolite in the matrix of PSf. Moreover, characterization of fabricated membranes was carried out using SEM, FTIR, zeta potential, pore size and water contact angle measurement. Adsorption and filtration experiments were conducted to evaluate the permeation performance of the membrane. Obtained results of permeation study reveal that the presence of clay minerals in the matrix of modified membrane not only increases the adsorption and rejection efficiency for Cu (II) but, it also improves the flux of pure water. Among all developed membranes, the membrane prepared by the mixing of zeolite demonstrates the highest adsorption (2.82 mg/g) and rejection value (97%) towards Cu (II) at low pressure (0.5 bar). Regeneration performance results confirm the reusability of membrane up to 3–5 cycles along with 82.5–90% metal recovery. Based on significant metal recovery, clay-based low-cost zeolite/PSf membrane could be used to remove Cu (II) from water at low pressure to replace current conventional membrane.

本研究的重点是制备用于处理Cu（II）离子的聚砜（PSf）-粘土矿物浸渍杂化膜的制造。通过将膨润土，海泡石和沸石混合在PSf的基质中，已经采用了共混和相转化的方法来开发粘土基膜。此外，使用SEM，FTIR，ζ电势，孔径和水接触角测量来对所制备的膜进行表征。进行吸附和过滤实验以评估膜的渗透性能。渗透研究的结果表明，改性膜基质中粘土矿物的存在，不仅提高了对铜（Ⅱ）的吸附和截留效率，而且还提高了纯水的通量。在所有已开发的膜中，通过沸石混合制备的膜在低压（0.5 bar）下表现出对铜（II）的最高吸附（2.82 mg / g）和截留率（97％）。再生性能结果证实了膜的可重复使用性高达3–5个循环以及82.5–90％的金属回收率。基于显着的金属回收率，基于粘土的低成本沸石/ PSf膜可用于在低压下从水中去除Cu（II），以替代当前的常规膜。
