Title: Method for separately collecting ion by electrically attractive force
Inventor: NISHIMURA SAKANORI
IPC: C02F1/48
Filed: 2000-02-28
Abstract: PROBLEM TO BE SOLVED: To collect/obtain useful materials in seawater or the like and to desalinate seawater by concentrating the ions in seawater, which are permeated through a diaphragm 2 and moved toward the electrodes, in the vicinity of each electrode 1 by impressing the prescribed voltage between the electrodes 1 covered with an insulator by making good use of electrically attracting force. SOLUTION: Since the surfaces of the electrodes are covered with the insulator, the ions moved in the solution can be collected around each electrode and withdrawn as the concentrated ion-containing aqueous solution. Since electric power is not consumed so much, seawater or the like can be concentrated or desalinated at a low cost.
