Abstract
Stannic arsenate thin layers (0.25 mm) have been applied for the chromatographic studies of 42 metal ions without using any binder. As a result, some important binary separations, such as Cd-Sb, V-Nb, V-Ta, Ni-Fe, Pd-Nb, Hg-Pb, and Pb-Mo, have been performed. Quantitative separation of Hg from Cd, Zn, and Cu has also been made by this technique. The study has been found to give reproducible results on refluxed and nonrefluxed samples of stannic arsenate used simultaneously.
