Abstract:

The advancement of forward osmosis (FO) technology can be promoted greatly with appropriate draw solutes. In this study, a series of piperazine-based ionized functional materials (PIFMs) with three-dimensional configurations are designed for FO desalination. All PIFMs produce high FO water fluxes with negligible reverse solute diffusion in which 1,4-piperazinediethanesulfonic acid disodium salt (P-2SO3-2Na) at 1.0 M generates a water flux up to 76.4 LMH against the feed of DI water. With saline water (0.1-3.5 wt % NaCl) as the feed, P-2SO3-2Na produces water fluxes of 11.3-35.0 LMH, sufficient for handling a large quantity of saline water. In FO seawater desalination P-2SO3-2Na produces a water flux 25-77% higher than recently proposed synthetic draw solutes. The characteristics of abundant ionic groups coupled with a three-dimensional configuration account for the good FO performance of PIFMs draw solutes. Copyright © 2018 American Chemical Society.
