Title:
混合イオン交換樹脂の分離方法
Document Type and Number:
Japanese Patent JP4346214
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To separate mixed ion exchange resins into a pure cation exchange resin and a pure anion exchange resin by arranging upper and lower resin collectors in a column near the calculated separation interface of the anion and cation exchange resin layers after stratiform separation and installing a resin withdrawing nozzle between the upper and lower resin collectors. SOLUTION: The upper resin collector 7 is arranged at the position upward by about 100-500 mm from the calculated separation interface 6, of the cation exchange resin layer 4 and the anion exchange resin layer 3, which is calculated from the amounts of both ion exchange resins to be introduced into the separation column 1. The lower resin collector 8 is arranged at the position downward by about 50-300 mm from the interface 6. These collectors 7, 8 are arranged by penetrating the column wall. The resin withdrawing nozzle 9 is installed between the collectors 7 and 8 near the interface 6, preferably at the interface 6 or at the little downward position from the interface 6.
