Other claims from this paper (6)
- Observation Higher valency cations were favored.
- Observation Selectivity rose with pH until full ionization.
- Observation At full ionization the selectivity order was Na–Ca, Na–La, then Ca–La.
- Observation Some isolated sites were neutralized more effectively by lower valency cations.
- Observation Strontium and calcium bound approximately equally.
- Observation Calcium binding was favored over magnesium.
