Fabrication, Characterization and Mechanical Stability Performance Test of Cellulose Acetate Membrane Filled with Lampung Natural Zeolite (Ca/LNZ)

Abstract

The hybrid membranes for pervaporation of ethanol-water mixture were prepared by filled Lampung natural zeolite (LNZ) into cellulose acetate (CA) casting solution in the varied ratio of CA:LNZ (30:0, 30:5, 30:10, 30: 20, 20:20 and 40:10) wt%. The effect of zeolite addition on the resulting membranes were characterized by using Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA) and scanning electron microscope (SEM) and X-ray-diffraction (XRD) analysis, which aims to observe the crystallinity, morphology, and thermal and mechanical stability of hybrid membrane. The results show that the interaction between the LNZ particles and CA were making the thermal stability, crystallinity, and hydrophilicity of the hybrid membrane improved compared with pure CA membrane.
