J. Lehto et R. Harjula, EXPERIMENTATION IN ION-EXCHANGE STUDIES - THE PROBLEM OF GETTING RELIABLE AND COMPARABLE RESULTS, Reactive & functional polymers, 27(2), 1995, pp. 121-146
The experimental procedures for the determination of the most importan
t equilibrium parameters of ion exchangers (ion exchange capacity, ion
exchange isotherm, selectivity coefficient, distribution coefficient)
are reviewed and discussed. Special emphasis is put on inorganic ion
exchangers and ion exchange at trace concentrations. Experimental deta
ils that are sensitive for obtaining accurate and reliable equilibrium
data are examined. In addition, the effects of physical and chemical
phenomena that may distort the results of ion exchange equilibrium stu
dies are examined and some guidelines are given on how to avoid these
interferences.
