摘要：

The system water-Cuprophan(R) has been studied by infrared spectroscopy, sorption isotherm and X-ray spectroscopy. It is concluded that near saturation water sorbed in the membranes has a comparable degree of association that approach that of liquid water. Similar conclusions can be derived from the form of the sorption isotherm and infrared data for water dissolved in organic solvents with a high hydrogen-bond acceptor capacity. The state of water in Cuprophan explains the larger solubility of ions and other solutes compared to Cellophan and Cellulose acetate membranes.
