| titleOfInvention | METHOD FOR ION EXCHANGE SEPARATION OF COPPER (II) AND NICKEL (II) IONS |
| abstract | The method of ion-exchange separation of copper (II) ions and nickel (II), characterized in that the separation of copper (II) ions and nickel (II) is carried out in three stages using one type of ion-exchange resin in OH-form, sorption is carried out at the first stage mixtures of metal ions with enrichment of the sorbent phase, for this purpose a Purolite S950 polyampholyte in OH - form is prepared, a mixture of two metal ions is sorbed in a countercurrent column with a fixed layer of sorbent, for this a solution containing the initial mixture is passed from below, sorption is stopped when e Yuate ion mixture, the sorption process is controlled by sampling, determining the total concentration of copper (II) and nickel (II) by the complexometric method, in the second stage, copper (II) ions are eluted with a glycine solution, which is fed from above, an eluate containing a complex of glycine and copper ions (II), collected in the receiver, at the third stage, the nickel ions are completely desorbed (II) with a KOH solution, which ensures regeneration into the initial form and the polyampholyte is ready for work. |
