Abstract

A solution of acylated polyethylenimine can absorb CO₂ at low temperatures to elevate the osmotic pressure and draw water from a high-salt saline solution. Such a solution can be phase-separated to liberate CO₂ by mild heating at 40°C, and the osmotic pressure can be effectively reduced for water release into a low-salt saline solution. The osmotic pressure-controlling system has the potential to be used as a draw solution for forward osmosis.
