TL;DR: In this article, Dimethylsulfoxide has been used to resolve such binary mixtures as La3+ and Ce3+ from Pr3+, Nd3+, and Sm3+; VO2+ from Ti4+, Nb5+, and Ta5+; Ga3+, from In3+, Tl+, and Y3+, Fe3+from VO2+, and Mg2+, from Al3+.
Abstract: Thin-layer chromatography of 40 metal ions in 31 aqueous and mixed solvent systems has been performed on stannic antimonate ion-exchange material. Dimethylsulfoxide has been utilized to resolve such binary mixtures as La3+ and Ce3+ from Pr3+, Nd3+, and Sm3+; VO2+ from Ti4+, Nb5+, and Ta5+; Ga3+ from In3+, Tl+, and Y3+; Fe3+ from VO2+; and Mg2+ from Al3+. Quantitative separation of 200 to 800 μg U from its binary mixtures and from the synthetic mixtures containing Mg2+, Bi3+, Fe3+, Th4+, Ce4+, Cr3+, Zr4+, Hf4+, Ti4+, Mn2+, Cu2+, Ce3+, In3+, Y3+, Ca2+, Co2+, Tl+, Nb5+, and Ag+ has been obtained.

TL;DR: An abundance of acid phosphomonoesterase in various parts of the alimentary canal and various organs of the reproductive system is revealed and the excretory ducts show alkaline phosphomonoeterase activity only.
Abstract: Biochemical and histochemical studies have been made on non-specific acid and alkaline phosphomonoesterases of S. dentatus. The two forms of acid phosphomonoesterases have been found active at pH 4.0 and 6.0. The pH optima for the two forms of alkaline phosphomonoesterases lie at 8.0 and 10.0. Studies on the distribution of acid and alkaline phosphomonoesterases in various tissues have revealed an abundance of acid phosphomonoesterase in various parts of the alimentary canal and various organs of the reproductive system. The excretory ducts show alkaline phosphomonoesterase activity only.
