摘要：

Carbon nanotube enhanced membrane distillation (MD) is presented as a novel waste concentration method that also generates pure water. In a carbon nanotube immobilized membrane (CNIM), the CNTs serve as sorbent sites, and provide an additional pathway for enhanced water vapor transport. Enrichment effect and mass transfer coefficients using CNIM were as much as 421% and 543% greater than in membranes without the nanotubes. As compared to the original water, the purified water contained less than 10% of residual organics. (C) 2012 Elsevier B.V. All rights reserved.
