Abstract: An ion exchanger filled cartridge accommodated inside an accommodating container of a metal removing column and in which an ion exchanger is filled is provided. The ion exchanger filled cartridge includes a cylinder portion, an upper lid in which a through hole for a liquid to be treated is formed and which is provided on an upper end of the cylinder portion, a lower lid in which a through hole for a treated liquid is formed and which is provided on a lower end of the cylinder portion, an insertion pipe connected to the lower lid, having an O-ring attached to an outer side, and inserted into a treated liquid discharge pipe provided on a bottom portion of the accommodating container of the metal removing column, and the ion exchanger filled inside the cylinder portion.

Abstract: A method for purifying an organic solvent has a first treatment of bringing an organic solvent to be treated into contact with an H-type cation exchanger, and a second treatment of bringing a treated liquid from the first treatment into contact with an anion exchanger and an H-type strongly acidic cation exchanger. According to the present application, the provided method and an apparatus for purifying an organic solvent remove metal impurities of both metal species of monovalent and polyvalent metals in the organic solvent.

Abstract: A method for purifying a nonaqueous liquid substance includes: filling a cartridge container with a macroporous or porous type ion exchange resin in a water-wet state to obtain an ion exchange resin-filled cartridge filled with the macroporous or porous type ion exchange resin before water content reduction; reducing a water content of the macroporous or porous type ion exchange resin in the cartridge container until a water content (A) of the macroporous or porous type ion exchange resin after water content reduction becomes 90 to 97% of a water content (B) of the macroporous or porous type ion exchange resin in a saturated equilibrium state; an initial blowing step of allowing the nonaqueous liquid substance before being purified to pass inside the cartridge container filled with the macroporous or porous type ion exchange resin after water content reduction and discharging an initial blow effluent from inside the cartridge container; and purification.
