摘要：The process of recovering water, salts, and toxic dyes from intricate saline textile wastewater faces difficulties in isolating dissolved ionic substances and reclaiming organic components during the desalination process. In this work, 2,4,6-Trimethyl-m-phenylenediamine (TMPDA) was employed to react with trimesoyl chloride (TMC) through interfacial polymerization reaction to fabricate nanofiltration membrane. Molecular dynamic simulation results show that the TMPDA with unique trimethyl groups has slower diffusion rate, forming a honeycomb-like structure and loose selective layer with more free volume. The obtained TMPDA/TMC membrane exhibits a high permeance of 113.8 L m(-2)h(- 1) bar(-1), high CR rejection (99.6 %) and low salt rejection (< 5 %), as well as excellent stability and anti-fouling performance. Our work sheds light on the fabrication of loose nanofiltration membrane with specific functional monomer and offers a potential application in the treatment of dye wastewater.
