Decomposition of lead nitrate in nitrate melts in the presence of titanium dioxideThe interaction between titania and lead nitrate has been studied in molten sodium and potessium nitrates medium. The formation of tetragonal lead metatitanate has been established. The rate of the formation and the ...
The Gd3+ doping would increase the average ion radius of rare earth, when the content of Gd3+ is over 60% will result in the decomposition of [(Lu1-xGdx)0.975Dy0.025]AG to [(Lu1-xGdx)0.975Dy0.025]AlO3 and Al2O3 compounds20; (2) the spherical morphology could not be kept if the...
Nitrate has been shown to have no effect in the presence of NaAsA. Nitrous acid (HNO2) degradation may take place through either autodegradation or reductive degradation, the latter being mediated through a compound such as NaAsA. Reductive degradation occurs more quickly compared to auto...
The catalytic cell comprises a column embedded with a catalyst (Fig. 1, right) that facilitates the catalytic decomposition of bromate anions (\({{\rm{BrO}}}_{3}^{-}\)) into bromide (Br–) and oxygen: $${2{\rm{BrO}}}_{3}^{-}\to {2{\rm{Br}}}^{-}+{3{\rm{O}}}_{2...
The cupric ion (Cu(II)), in the presence of superoxide anion radical or biological reductants such as ascorbic acid or GSH, can be reduced to cuprous ion (Cu(I)) which is capable of catalyzing the formation of reactive hydroxyl radicals through the decomposition of hydrogen peroxide via the...
A description is given of an apparatus of simple construction that can be made from plastic, in which the decomposition of silicate materials by hydrofluoric acid can be carried out. The procedure for the titration of iron(II) with dichr... HNS Schafer - 《Analyst》 被引量: 42发表: 1966...
The reduction of oxygen on nickel-cobalt oxides—I: The influence of composition and preparation method on the activity of nickel-cobalt oxides Nickel cobalt oxides were prepared by coprecipitation, freeze drying and nitrate decomposition. The resistivity, surface area, crystal structure and electr.....
decomposition of Ca-containing organs,and it shoud not have higher concentrations than 250mg/L.In areas where quartzitic sand or sandstone or acid igneous rocks such as granites or rhyolites are outcropping surface-and groundwater have very low calcium contents.Areas with high calcium concentrations...
The gases must be added sub-stoichiometrically to avoid quantitative decomposition of the AC [10]. The addition of carbon dioxide leads to a pore opening at a later stage of the activation process, which involves widening of the narrow microporosity, whereas the addition of water vapor widens ...
A total of 5 µL of a 5% methanolic solution of tetramethylammonium hydroxide (TMAH) was added to approximately 80 µg of solid sample to promote total thermal decomposition of the binder chain, especially alkyds. Nonadecanoic acid was added as an internal standard to follow degradation ...
