“…However, no information is available on chemical forms of much more dilute Sb(V) in a chloride solution such as was used in this experiment. By absorption Mössbauer spectroscopy, RUBY et al showed that the Sn 4 + ions are surrounded by six H 2 O molecules in rapidly frozen dilute solutions of SnCl 4 [12]. In our emission Mössbauer study of 119 Sb-119 Sn, analysis is made on the 23.9 keV γ-rays emitted by 119 Sn nuclei in the first nuclear excited state 19 Sn*, half-life: 17.8 ns) arising from 119 Sb (half-life: 38.0h) by the EC decay.…”

The pH dependence of adsorption of no-carrier-added "'Sb(V) ions from a 0.25 mol dm" 3 LiCl aqueous solution ontoCr 2 0 3 , α-Al,0 3 , γ-Fe,Ο,, Fe 3 0 4 , CoFe 2 0 4 , NiFe 2 Ο,, and a-FeOOH powders as well as respective adsorption kinetics was studied. The 119 Sb (V) ions were adsorbed by the adsorbents only in the acid pH range. The adsorption proceeded with kinetics measurable by a conventional radioanalytical technique and increased with elevation of temperature. The adsorption kinetics of 119 Sb(V) ions are found to obey rate formulae with different characteristics depending on the adsorbents. Emission Mössbauer spectra of 119 Sb (V) in the frozen solution revealed that the 119 Sb(V) ions are coordinated only by oxygen atoms. In electrophoresis, most of the 119 Sb(V) ions migrated toward the anode. These observations suggest that anionic species of 1I9 Sb(V) ions are involved in the adsorption.

“…A similar tendency was observed for the am m onium salt. Presumably, hydrolysis of the com plex anion takes place in solutions of weak acidity [10] which may lead to a weakening of the N Q R signal intensity. Therefore, we prepared the mixed crystal from solution of SN hydrochloric acid and we 0340-4811 / 86 / 0100-0326 $ 01.30/0.…”

The temperature dependence o f 35C1 N Q R frequencies was measured on the mixed crystal [(N H 4)00|Kp99]2SnCl6. Two phase transitions have been located at 7"cl = 259K and J ' c2 = 252K , which are lower by 3 K than the corresponding transition temperatures o f the pure K2SnCl6 crystal. The DSC experiments showed that the NH^ concentration dependence o f ?c2 almost parallels that o f Tc]. The impurity effect resulting from the inclusion o f a small amount o f N H f1 ions in K2SnCl6 crystals is discussed in relation to the m icroscopic viewpoint o f the phase transitions.

“…The result is in agreement with the findings of Merup 60 who concluded that aqueous solutions of Fe(NO) 3 , HNO 3 and NaNO 3 , frozen at a cooling rate of 570°C min -1 , attain an amorphous state, keeping the structure of the aqueous solutions unchanged. In addition, Ruby 61 noted that Mössbauer parameters of aqueous solutions of SnCl 4 do not show any difference at a cooling rate exceeding 8°C s -1 . This fact indicates that "fast" freezing is freezing characterized by a rate of cooling ≥ 8°C s -1 .…”

The application of fast-atom bombardment (FAB) mass spectrometry to solving the problems of heterogeneous atmospheric chemistry is briefly reviewed. The method is useful in studying the state of surfaces and molecules adsorbed thereon and looks appropriate in investigations of the dynamics and mechanisms of chemical reactions occurring both on a surface and in a volume of moving particulate matter suspended in a gas. It was shown that composition of atmospheric aerosols and components dissolved in atmospheric water (clouds, fogs, mists etc.) can be determined by the FAB technique. The given method, as was found in our investigations, allows the discrimination of ferrous and ferric ions. Detection limits for concentrations of H2SO4 and Fe(II / III) ions as essential components of atmospheric water determined in model experiments are established at the level of 10−6 M.
