Method and apparatus for recovering Cr (VI) from anion exchange resin tower |
| abstract |
(57) [Summary] [PROBLEMS] To enable impurities in a recovered Cr (VI) solution to be easily reduced and to be usable as a raw material for producing chromium salts. SOLUTION: Anion exchange resin tower 5 saturatedly adsorbing SO 4 2− and Cl − ions in addition to Cr (VI) ions. Through a concentrated solution of Cr (VI) through SO 4 2− , Cl − A method for recovering Cr (VI), comprising a step of extruding ions and the like, and a step of recovering only Cr (VI) at a high concentration by performing a countercurrent multistage regeneration method after this step. |
