Methods The measurements were carried out by batch equilibration, most by an isotope dilution technique. Samples of clay were pre-equilibrated several times with NaCl-CaCl2 solutions of fixed compositions, until successive equilibrations showed no change in concentration. To separate samples (separate because of he difficulty of discriminating between the gamma emission of Na and Ca radioisotopes) were added known amounts of Na and Ca tracers, and the solutions were allowed to equilibrate for 2-5 days. The solid was centrifuged down, and aliquots of the supernatant solutions were counted. By material balance, the fractions of the activity adsorbed were computed, and, from these, the distribution coefficients, D... [Pg.698]
