<P>PROBLEM TO BE SOLVED: To provide a method for separating the mixed resin of a mixed bed resin packed column, capable of enhancing the separability of an anion exchange resin and a cation exchange resin. <P>SOLUTION: The method for separating the mixed resin of the mixed bed resin packed column packed with the mixed resin of the cation exchange resin and the anion exchange resin is constituted by combining a backwashing step A for allowing the mixed resin to flow at linear flow velocity (LV) preventing the mixed resin from reaching the column top part of the mixed bed resin packed column to perform backwashing and a backwashing step B for performing the backwashing of the mixed resin at linear flow velocity (LV) for allowing the mixed resin to reach the column top part of the mixed bed resin packed column, thereby separating the mixed resin into the cation exchange resin and the anion exchange resin. <P>COPYRIGHT: (C)2012,JPO&INPIT |
