摘要:
SummaryThe exchange reaction between NH4+and Mn3+was studied on a montmorillonite clay at several temperatures and different ionic strengths.Manganese was preferred to ammonium; this preference increased with the temperature and dilution of the dialysate. Comparison with published data concerning exchanges involving NH4+and the alkaline‐earths showed that in the sequence of increasing selectivity: Mg2+
