摘要

The distribution coefficients D_(2/1) (Henderson-Kracek, Chlopin) of trace amounts of ions M~(2+) { Ni~(2+), Mg~(2+), Cu~(2+), Co~(2+), Mn~(2+), Cd~(2+), Ca~(2+)} with ZnSeO_4·6H_2O have been determined. The values of D_(2/1) range from 2.93 (for Ni) to ＜ 0.03 (for Ca), but most of them are nearly 1 and corresponding ions cannot be effectively removed from ZnSeO_4 · 6H_2O during its crystallization. The dependences of coefficients on various chemical and crystal chemical factors have been analyzed. It has been found that ionic radii, parameter μ as well as number of molecules of crystallizing water affect significantly D_(2/1) coefficient. It has been proved possible to derive an empirical formula, which permits estimating D_(2/1) coefficients at average relative error not exceeding 25%.
