Essay

The thesis is devoted to the experimental research of adsorption processes of molybdenum(VI), tungsten(VI) and vanadium(V), which occur owing to complex formation on a surface of chemically modified silica gels with grafted amino- and mercaptopropyl groups, and silica gels, which are modified by complexing organic reagents at the expense of the physical sorption. The optimal conditions of sorption of binary (metal - organic reagent) and triple (metal - organic reagent - surface-active substance (SAS)) complexes on the surface of aminosilica gels are determinated. It is shown, that adding of SAS with hydrocarbon radical length of С 12 assists in the quantitative extraction of analyzed metals. At that a bathochrome shift of absorption bands maxima of obtained on a surface complexes in diffuse reflection spectra is observed.
