Abstract
The sorption of cobalt ion on calcium-montmorillonite was studied by t he radioisotopic tracer method at different pH values. In dilute solut ions the reaction has to be treated as a ternary exchange of cobalt, c alcium, and hydrogen ions because of the high affinity of hydrogen ion to montmorillonite. Equilibrium constant for calcium-hydrogen exchang e was determined. (C) 1997 Elsevier Science B.V.
