摘要

Abstract

A novel mixed matrix nanofiltration membrane was constructed by coating a casting solution containing polyvinylidene fluoride (PVDF)

polyethylene glycol (PEG) as hydrophilic agent

zeolitic like framework-67 (ZIF-67)

ethylenediamine as cross-linking agent on Ag-nanoparticle-decorated polyester textile (PT) support (PT/AgNPs/PVDF-PEG/ZIF-67). PT/Ag-NPs/PVDF-PEG/ZIF-67 morphology

crystalline structure

surface chemical composition and hydrophilicity of PT/Ag-NPs/PVDF-PEG/ZIF-67 were fully characterized by field emission scanning electron microscopy (FE-SEM)

X-ray diffraction (XRD)

Fourier transform infrared spectroscopy (FT-IR) and water contact angle technique

respectively. PT/Ag-NPs/PVDF-PEG/ZIF-67 was applied in cross module set-up for removal of contaminated water containing rose bengal (RB) dye. The effect of operational parameters such as dye concentration

solution pH and flow rate on performance of PT/Ag-NPs/PVDF-PEG/ZIF-67 were investigated and optimized by central composite design (CCD). Casting solution containing 0.5 wt.% ZIF-67 as optimum value showed the good wettability

high pure water flux (PWF; 35.8 L·m

)

flux recovery ratio (FRR;90%)

dye removal efficiency (96.41%). The selectivity factor of 12.72 and 14.42 was found to be for RB in the presence of amido black and methylene blue as interferent dyes

respectively

which showed a good selective recognition ability for RB dye.
