| titleOfInvention | A method for separating and recovering acid and metal ions in iron and steel pickling waste liquor |
| abstract | The invention discloses a method for separating and recovering acid and metal ions in iron and steel pickling waste liquid. In the chromatographic separation column of the material, the effluent is collected in three sections, which are the effluent of the low-concentration recovery area, the effluent of the ferrous ion recovery area and the effluent of the original concentrated recovery area; (2) Elution: elution with the eluent , collect the eluates in three sections, which are the eluate of the original concentrated recovery area, the eluate of the acid recovery area and the eluate of the low-concentration recovery area; (3) Repeat the cycle step (1) and step (2) until the solid The cycle is stopped when the phase separation material has no separation effect on acid and ferrous ions. Compared with the prior art, the technical process of the invention is reasonable and controllable, the equipment requirement is low, the separation efficiency is high, the acid recovery rate is higher than 95%, and the metal ion recovery rate is higher than 98%. The acid recovery concentration c t /c 0 ≥ 80%, and the metal salt recovery concentration c t /c 0 ≥ 90%. |
