Abstract

This paper reports the development of novel carbon nanotube immobilized composite membranes (CNIMs) for the extraction of volatile organics from air. The nanotubes were immobilized onto the selective layer of a composite membrane where they served as sorption sites and provided additional pathways for enhanced solute transport. Depending upon the process conditions, the presence of carbon nanotubes led to the organic removal with flux as high as 37.7 × 10^-5, 72.9 × 10^-5, and 8.22 × 10^-5 gm-mol/m²-min and an increase in mass-transfer coefficient of about 92.2%, 22.7%, and 44.3% for toluene, dichloromethane, and ethanol, respectively. The CNIMs demonstrated several advantages, including enhanced recovery at low concentrations and low temperature.
