“…Tel. (7-095) 137 28 78 (S B Savvin), (7-095) 939 70 73 (V P Dedkova, O P Shvoeva) lisation of the reagent on the carrier, on kinetic features of the process and on many other factors. 7 ± 10 Depending on the method used to detect the analytical signal, sorption-spectroscopic methods for the determination of elements with the use of modified ion-exchange resins (solid-phase spectrometry) are subdivided into sorption-luminescent, sorptionphotometric and diffuse reflectance spectroscopy.…”

“…26 A study of formation of mixed-ligand complexes of Zn(II), Cd(II), Pb(II) and Ag(I) on silica modified with thiourea derivatives revealed that the rate of formation of such surface complexes depends on the ratio of stability constants of metal ± ligand complexes in solutions. 27 Modified silica is used for the determination of osmium(VIII) and palladium(II) in wet dedusting sludge and washing acids 28,29 and for the determination of gold. 30 Gold is determined as the metal after thermal treatment of the sorbent and osmium is determined as the oxide.…”

“…A similar conclusion was made by the same authors from the studies of the recovery of osmium in different oxidation states by sorption on silicas with grafted thiourea derivatives. 23 Organosilicon adsorbent 1 containing thiol groups was also used for low-temperature sorption of gold for subsequent luminescence determination. 24 The adsorbent was prepared by immobilization of mercaptopropyl(triethoxy)silane on silica gel for column chromatography (Merck, fraction of 0.06 ± 0.16 mm, specific surface area *500 m 2 g 71 , average pore diameter 6 nm).…”

Data on the ion-exchange and complexing orga-Data on the ion-exchange and complexing organosilicon adsorbents published during the last 10 ± 12 years, nosilicon adsorbents published during the last 10 ± 12 years, including the results of systematic research of the authors, including the results of systematic research of the authors, are summarized and analyzed. The following types of are summarized and analyzed. The following types of substances are considered: silicas with covalently grafted substances are considered: silicas with covalently grafted modifiers, silicas and aluminosilicates with non-covalently modifiers, silicas and aluminosilicates with non-covalently grafted modifiers and carbofunctional polyorganylsilses-grafted modifiers and carbofunctional polyorganylsilsesquioxanes prepared by polycondensation of appropriate quioxanes prepared by polycondensation of appropriate organosilicon monomers. Adsorbents of these types find organosilicon monomers. Adsorbents of these types find extensive practical use, in particular, as analytical reagents extensive practical use, in particular, as analytical reagents for determination of metals in natural and artificial speci-for determination of metals in natural and artificial specimens, agents for isolation of valuable elements from indus-mens, agents for isolation of valuable elements from industrial wastes and agents for removal of especially hazardous trial wastes and agents for removal of especially hazardous components from wastes and effluents.

“…[15][16][17] Although osmium is frequently stabilized by addition of chloride or HCl, osmium can still occur in HCl solutions as various species of different oxidation states. 18 A recent study on the topic demonstrates that the collective determination of Os together with the elements required by h232i following oxidative digestion is difficult and even prone to errors. 19 Therefore, for the collective determination of all elements required by h232i including Os a simple and effective method of stabilisation for Os is required.…”
