comparatively large Mg2+ ions diffused much more slowly than the smaller, monovalent Li+ ions. In addition to sterical hindrance within the small channels, the large hydration shell of Mg2+ also hindered their ... extraction is its separation of its monovalent ion (carrying one positive charge) from other ions with 2 or more positive charges ...
