| Abstrakt: |
The behaviour of mono and diquaternary ammonium cations during extraction and precipitation of CoCI4 2 ions is used to clarify some aspects of the secondary effects present during their operation. A quantitative treatment of the "HCI effect" is offered. It is illustrated that this effect must be ascribed to a lowering of the activity of the cation rather than formation of undissociated acid species like H2CoCI4 |
