The Role of Ion Exchange Membranes in Membrane Capacitive Deionisation
Membranes, 2017 Ion-exchange membranes (IEMs) are unique in combining the electrochemical properties of ion exchange resins and the permeability of a membrane. They are being used widely to treat industrial effluents, and in seawater and brackish water desalination ...

Membrane Potentials and Ion Permeability in a Cation Exchange Membrane
Biophysical Journal, 1971 The nonequilibrium electrical potentials across an artificial membrane bathed by solutions of a single salt have been measured and calculated using the Goldman-Hodgkin-Katz equation and the irreversible thermodynamic equation. The latter equation predicts the observed potential differences over a 2500-fold concentration range, while application of a ...

Self-diffusion of a Cation through Cation Exchange Membrane and Membrane Permeability [PDF]
Bulletin of the Chemical Society of Japan, 1973 Abstract The self-diffusion coefficient of an ion and the membrane permeability were studied with a system consisting of two identical electrolyte solutions separated by a cation exchange membrane. The membrane permeability to cation was estimated from the membrane conductance data.

Permselectivities of Cation-exchange Membranes
The Journal of the Society of Chemical Industry, Japan, 1960 強酸性樹脂および強塩基性樹脂より製造した不均質イオン交換膜における典型的な陽イオンの選択透過性を, 7 室電解槽により検討した。各室は予かじめ原液をみたしておき,希釈室では液を下方から上方へ流しつづけながら一定電流密度(2A/dm2)で電解透析を行ない,真中の濃縮室の試料液について毎時間ごとに各イオンの定量を行なった。イオンとして2成分系は(Na,Ca),(Na,Mg),(Ca,Mg),(NH4,Mg)の4種類について,3成分系ではCa2+,Mg2+を共通成分として,第3成分としてそれぞれH+,K+,NH4+,Na+を加えて行なった。原液の濃度は各成分約0,05Nを標準とし,Na+のみ例外的に0.5Nとした。2～4時間の電解透析において選択透過係数,すなわち当該イオンの濃縮比の比を比較した結果 ...
