Abstract

Pervaporation (PV) is highlighted in recent research as an attractive and promising membrane process for desalination. However, the permeability is thought to be low for practical application. Incorporating a hydrophilic nanofillers to develop a composite membrane potentially improves the productivity, selectivity and thermochemical durability of a membrane. CNCs are a renewable material with low cost and thought to be attractive for reinforcing polymers and increasing the hydrophilicity of nanocomposite materials. In this study, nanocomposite membranes were prepared by incorporating CNCs into cellulose triacetate (CTA) by solution casting in order to enhance the performance of pervaporative desalination. The resulting membranes were characterized by scanning electron microscope (SEM), atomic force microscope (AFM), water contact angle, tensile strength, and Fourier transform infrared (FTIR) spectroscopy. The desalination performance by vacuum pervaporation was investigated as a function of CNCs loading, feed temperature (30 and 70°C) and feed concentration (from 30 g/L to 90 g/L NaCl)
