Popis: | Synthesized are hybrid organoinoragnic adsorbents based on organic resins Dowex SBR-P, Dowex Marathon II and hydrated oxides Zn(IV), Ti(IV), Sn(IV) and Fe(III). Specific conductivity was measured of the specified resins and hybrid organoinorganic adsorbents in the initial form and after absorption of ions As(V) from 10–2 M aqueous solution of NaH2AsO4. Introduction of hydrated tin oxide increases ionic conductivity of organic resin Dowex SBR-P by 2.5 times. During the conversion to the arsenate form the conductivity of hybrid adsorbents changes insufficiently at the adsorption from the solution with pH 7 and increased by 2–10 times at adsorption from the solution with pH 2. |
