RECOVERY METHOD OF IONIC LIQUIDS IN AQUEOUS SOLUTION USING MEMBRANE CAPACITIVE DEIONIZATION

摘要

The present invention relates to a collection method of an ionic liquid which exists in an aqueous solution by using a membrane capacitive deionization cell (MCDI cell). The present invention has an eco-friendly effect and ensures to spare expenses on collecting the ionic solution since it is possible to collect the ionic liquid at a high recovery rate from the treated water containing a small amount of the ionic liquid while not producing salts such as by-products in the collected ionic liquid, and to regenerate electrodes of MCDI cells without other treatments such as acid or base.
