Abstract
Microcalorimetric measurements were carried out on the heat effects of ion exchange in a system containing natural heulandite and aqueous solutions of pairs of electrolytes at 303.15 K. The electrolytes studied were NaCl, KCl, RbCl, CsCl, and NH 4 Cl. The ion exchange enthalpy decreases in the cation series: Na+ > NH4 + > K+ > Rb+ > Cs+.
