Analytical separations metal sulfides

The solubility of the group S(a) sulfides in an excess of sulfide ions is well established and used for analytical separation procedures. For the group S(b) sulfides, however, there are few reports in the older literature regarding their solubility in alkali metal sulfide solutions. [Pg.525]

Under physiological conditions, as well for trace analytical procedures, no precipitations are considered coprecipitations, however, can be used for analytical separations (Sager, 1986 Sager, 1992). In the system Tl-S, 8 different phases are known besides mixed sulfides with other metals (Fialkov and Muzyka, 1952). TI2S can add elemental sulfur as well as polysulfide, which lowers its solubility, in open air, on the other hand, TI2S is easily oxidized to soluble TI2SO4. Monovalent thallium forms stable com-... [Pg.501]
