The cation exchange equilibrium in the systems of natural heulandite-binary aqueous solutions of NaCl, NiCl2, CuCl2, ZnCl2, and MnCl2 was studied. The corrected coefficients of the selectivity (kaM/Na) and thermodynamic constants (KM/Na) of the cation exchange of Na+ cations for transition metal cations were determined. The selectivity of the cation exchange on natural heulandite increases in the following order: Ni2+ < Cu2+ < Zn2+ < Na2+ < Mn2+. |
