Abstract

Carbon nanotube (CNT) enhanced membrane distillation is presented for water desalination. It is demonstrated that the immobilization of the CNTs in the pores of a hydrophobic membrane favorably alters the water-membrane interactions to promote vapor permeability while preventing liquid penetration into the membrane pores. For a salt concentration of 34 000 mg L ^-1 and at 80 °C, the nanotube incorporation led to 1.85 and 15 times increase in flux and salt reduction, respectively. © 2010 American Chemical Society.
