- Abstract
The Np(V) distribution coefficients between montmorillonite and solutions of MgCl2 and CaCl2 were determined experimentally. The Np sorption decreases with increasing concentration of the supporting electrolyte. The sorption is very fast within the first several hours after the start of the experiment and then decelerates, reaching the equilibrium in approximately two weeks. The constants of binary ion exchange NpO-Mg2+ and NpO-Ca2+ on montmorillonite determined by fitting the experimental results are $$\log K_{NpO_2^ + - Mg^{2 + } } = 0.083 \pm 0.03$$ and $$\log K_{NpO_2^ + - Ca^{2 + } } = 0.106 \pm 0.014$$ .
