Removal of metal ions by extraction with a combination of an organophilic complexing agent and an organic solvent in the preparation of pulp |
| abstract |
A procedure in the manufacture of lignocellulose to remove non-process elements in the form of incrust forming alkaline earth metals and other metals and transition metals is described, the extraction with a combination of an organophilic chelating agent and an organic solvent being carried out in the production of chemical and mechanical pulps, and pulps from recycled fibres. |
