Description
  • V článku je popsána destrukční aktivita několika nanokrystalických směsných oxidů Ti, Zn, Al a Fe. Směsné oxidy byly připraveny metodou homogenní hydrolýzy sulfátů odpovídajících kovů ve vodném prostředí za přítomnosti močoviny při 100 °C. Připravené preparáty byly charakterizovány měřením BET a BJH, rtg. difrakcí a řádkovací elektronovou mikroskopií. Připravené oxidy byly hodnoceny na reaktivitu vůči sulfidickému yperitu (bis(2-chlorethyl)sulfidu), somanu (3,3´-dimethylbutan-2-yl)-methylfosfonofluoridátu) a látky VX (S-[2-(diisopropylamino)ethyl]-O-ethyl-methylfosfonothioátu). Byla zjištěna výborná reaktivita směsných oxidů vůči všem bojovým chemickým látkám se stupněm konverze vyšším než 96 % za dobu jednohodinové reakce. (cs)
  • Destruction activities of several nanocrystalline mixed oxides of Ti, Zn, Al and Fe are described in the article. The mixed oxides were prepared by a homogeneous hydrolysis of sulphates with urea at temperature of 100 °C in an aqueous solution. The prepared samples were characterized by BET and BJH measurements, an X-ray powder diffraction and scanning electron microscopy. These oxides were taken for an experimental evaluation of their reactivity with sulfur mustard (2,2'-dichloroethyl sulphide), soman (3,3-dimethyl-2-butyl methylphosphonofluoridate) and VX agent (O-ethyl S-2-(diisopropylamino)ethyl methylphosphonothionate). An excellent activity in decomposition of chemical warfare agents was observed in presence of these materials (conversion degree higher then 96% within one hour reaction).
