| titleOfInvention | Circulation concentrating method for producing highly concentrated iron chloride recycling waste etching solution |
| abstract | The present invention relates to a circulation concentration method for producing a high concentration of ferric chloride by recycling the waste etching solution. One aspect of the circulating concentration method for producing a high concentration of ferric chloride by recycling the waste etching solution according to an embodiment of the present invention, FeCl 2 And in recycling waste etching solution comprises a Ni: (A) phase is Fe 2 + ions present in the waste etching solution to be oxidized to Fe + 3 ions; (B) separating the organic phase containing Fe 3 + ions and the aqueous phase containing Ni 2 + ions by solvent extraction; (C) FeCl 3 from organic phase Recovering the aqueous solution; And (D) recovering NiCl 2 from the aqueous phase; (E) recovered FeCl 3 Concentrating the aqueous solution to a predetermined concentration or more; . |
