NaCl crystal from salt solution with far below saturated concentration under ambient condition
arXiv:1708.02994
Abstract
Under ambient conditions, we directly observed NaCl crystals experimentally in the rGO membranes soaked in the salt solution with concentration below and far below the saturated concentration. Moreover, in most probability, the NaCl crystals show stoichiometries behavior. We attribute this unexpected crystallization to the cation-Ï interactions between the ions and the aromatic rings of the rGO.
