Seawater Desalination via Hydrogels: Practical Realisation and First Coarse Grained Simulations

Popis výsledku v původním jazyce

We investigated and described a novel approach for water desalination using charged hydrogels under externally applied mechanical forces. The desalinationmechanism is based on the unequal distribution of an added salt between gel and surrounding solutionphase. We synthesised acrylic acid-based hydrogels of various compositions and investigated their desalination properties with a specifically designed experimental press setup that allowed us to control online the force respective pressure exerted on the gel and to measure the water elution from the gel bed as well as the salt concentration of the eluate. A reference sodium chloride solution was used as a model for desalination applications. The experiments were augmented with a theoretical analysis within a mean-field Donnan model that can semiquantitatively explain the salt distribution and the desalination process. In addition we performed coarse-grained simulations with explicit ions and charged bead-spring polymers. The simulation
