PURPOSE: To provide a method for removing dissolved contaminants from an organic solution by placing a module containing an ion exchange resin, activated carbon or their mixture between an organic solution dispensing container and the point at which the solution is to be used and then passing the solution through the module. CONSTITUTION: A dispensing means for dispensing the organic liquid, the target point at which the again solution is to be used and a purifying means comprising the module which is disposed between the dispensing means and the target point and contains a main element selected from the group consisting of the ion exchange resin, the activated carbon adsorbent and their mixture are prepared, in the purifying method of the organic solution containing dissolved contaminants. The organic solution from the dispensing means is transferred to the target point through the purifying means. The purifying means also includes a filtrating means disposed on the downstream of the module and contains a cationic or anionic exchange resin or activated carbon. Otherwise, the purifying means contains a mixture of anionic and cationic exchange resins and further activated carbon. |
