L., Registration Date 16-12-2008 Organization O.O. Chuiko Institute of Surface Chemistry of the National Academy of Sciences of Ukraine popup.description2 The purpose of this project - the combining effort to both research groups one from the Surface Chemistry Institute of of NASU (Kyiv, Ukraine) and one from Institute of general and inorganic chemistry of NASB (Minsk, Belarus) to develop basic scientific principles of creating procedures of the directed synthesis of sulfur-containing adsorption materials on the basis of mesoporous silicas. The further using of these adserbents distined for selective extraction ions of high-density and noble metals from agues and nonaqueous solutions. Next ways have been offered for achievement of the specified purpose: 1. Synthesis with using of template method; 2. Using multicomponent systems including sulfur-containing trifunctional silanes on the basis of thiourea derivatives; 3. Using expander agents with specially matching nature and geometry; 4. The synthesis carried out by one-step scheme. The factors which influence on composition, texture and properties including their selectivity relative extraction ionsof high-density metals have been established by methodical researches. On the basis of these factors the directed synthesis of novel sorbents and their subsequent comparative testing have been carried out. The practical recommendations for synthesis of such adsorption materials grounded on obtained data file have been proposed. Product Description popup.authors popup.nrat_date 2020-04-02 Close
