    Application of negative ions in inductively coupledplasma-mass spectrometry / A. A. Pupyshev, V. T. Surikov // Spectrochimica Acta B. - 2004. - Vol. 59. - P. 1021-1031 : il. - Bibliogr. : p. 1030-1031 (34 ref.)

СПЕКТРОМЕТРИЯ ПЛАЗМЕННАЯ -- ТЕРМОДИНАМИКА -- ИОНЫ ОТРИЦАТЕЛЬНЫЕ
Аннотация: The efficiency of the formation of negative background and F(-), Cl(-), Br(-) and I(-) ions in inductively coupled plasma (ICP) was investigated at temperatures ranging from 4000 to 9000 K using thermodynamic simulation. It was shown that the basic negative background ions in ICP, O(-), H(-), OH(-) and probably Ar(-), are in accordance with experiment. The estimated total concentration of negative ions in ICP was found to be four to five orders of magnitude smaller than that of positive ions. The highest efficiency of negative ion formation should be observed for elements having high electron affinity, namely Cl, F, Br and I. However, the detection sensitivity in the negative ion detection mode may be increased slightly as compared with the positive ion detection mode only for fluorine in the temperature range 6000–7000 K. This is in contradiction with experimental results and may be explained by the formation of negative ions behind the skimmer and/or smaller losses of negative ions in the ion beam at low ionic current. The relationship between the efficiency of negative atomic ion formation and electron affinity was determined. This makes it possible to estimate numerically the efficiency of the formation of Ar(-), Na(-) and other negative atomic ions in the ICP. The calculations performed confirmed the experimental data showing that the cation (Ba, Co, Cu, K, Na and Sr) introduced as a chloride does not affect the analytical signal of Cl(-). According to the calculations, high contents of halogens in samples are not expected to alter significantly the contents of F(-), Cl(-), Br(-) and I(-) measured in ICP as analytes. The experimentally observed significant suppression effect of high halogen concentrations may be caused by a shift of equilibrium in reactions of electron addition to halogen atoms behind the skimmer and/or increased negative ion current in the ion beam and accordingly greater losses of analytes

ГИДРОЛИТИЧЕСКОЕ ОСАЖДЕНИЕ -- ПОЛИВАНАДАТ КАЛЬЦИЯ
Аннотация: The effect of VO2+ ions on the composition and kinetics of calcium polyvanadate precipitation from solutions with 1.5≤pH≤9 at 80–90°C has been studied. For 1.5≤pH < 3 and V(4+)yV(5+) = 0.11–9, the precipitated compounds have the general formula CaVxV(4+)yV(5+)12-yO31–δ· nH2O (0.8 ≤ x ≤ 1.06, 2 ≤ y ≤ 3, 0.94 ≤ δ ≤ 1.5). The maximum vanadium(IV) proportion (y = 3) in the precipitates is achieved when V4+/V5+ = 0.5–1.0 in the solution and pH is 3. Polyvanadate precipitation at pH 1.7 has a long induction period (up to 30 min), which is not observed for V4+/V5+ > 0.1. Precipitation in solutions with pH 3 occurs only when VO2+ ions are added, with a maximum rate near V4+/V5+ = 0.2 and in presence of chloride ions. The processes are controlled by a secondorder reaction on the polyvanadate surface

ХЛОРИД ЛИТИЯ -- ГЕКСАЦИАНОФЕРРАТ ЦИНКА
Аннотация: Mechanisms of lithium chloride sorption by zinc hexacyanoferrate(II) Zn2Fe(CN)6· 2.5H2O in a nonaqueous medium (ethanol) were studied by chemical analysis, X-ray powder diffraction, wide-line 7Li and 1H NMR, vibrational spectroscopy, and impedance spectroscopy. The physicochemical properties of sorption products are reported. Lithium ions in the sorption products were found to be in a hydrated form. The accommodation of molecularly sorbed Li+aq · Cl–ion pairs in the bores of channels in the crystal structure results in the formation of a continuous network of hydrogen bonds and changes the proton transport mechanism. As the lithium chloride concentration increases in the temperature range 22–150 °C, the conductivity (σ) of sorption products increases three to four orders of magnitude to reach 10–3S cm−1

ЯДЕРНЫЙ МАГНИТНЫЙ РЕЗОНАНС -- ЯМР -- ХЛОРИД ЛИТИЯ -- ЦИАНОФЕРРАТЫ
Аннотация: The broadline 7Li and 1H NMR spectra of the sorption products of lithium chloride on zinc, lead, and tin cyanoferrates have been analyzed. Sorption of LiCl inside the Zn2Fe(CN)6 . 2.5H2O crystal structure proceeds first by the ionic exchange mechanism and then by the molecular sorption of Li+–Cl– ionic pairs. For Sn and Pb cyanoferrates, lithium choride is adsorbed on the surface. In all products as the LiCl content increases, the hydrolysis of cyanoferrates is intensified with the increase in the number of mobile protons

ХЛОРИД КАЛИЯ -- КРИСТАЛЛИЗАЦИЯ
Аннотация: A model of spontaneous crystallization process was proposed. The model describes kinetics of the crystallization process after the end of the induction period. To test the model the published earlier data on crystallization and aggregation kinetics of potassium chloride at its spontaneous crystallization from supersaturated aqueous and aqueous-ethanol solutions were used. It was found excellent coincidence of the experimental and theoretical data on concentration of the salt and the total number of crystals in solution at crystallization. Somewhat change for the worse was at the theoretical calculations of crystal size distribution at the end of the crystallization process. It indicated that the ways of calculation of size of crystals and their weight fraction in deposit were very approximate. The model allows predicting with satisfactory accuracy kinetics of crystallization using such general parameters of potassium chloride as the specific surface energy and the height of the nucleus-bridges between crystals at coalescence. It needs further test of the model for other salts

ХЛОРИД НАТРИЯ -- КРИСТАЛЛИЗАЦИЯ
Аннотация: The kinetics of spontaneous crystallization of sodium chloride from aqueous-ethanol solutions were studied. During the crystallization the electrical conductance and optical transmission of the supersaturated solutions were measured automatically. For monitoring of the total surface of growing potassium chloride crystals at the crystallization the turbidimetric method was used. The growth rate and activation energy were determined. The crystal growth rate was proportional to supersaturation. When the volume fraction of ethanol in solution increased from 14.85 to 29.72%, the activation energy of the growth process did not change and was about 50 kJ⋅mol-1. Aggregation of the crystals was found. The aggregation kinetics of the crystals may be described approximately by the famous Smoluchowski equation for coagulation of colloidal particles

ХЛОРИД КАЛИЯ -- КОАЛЕСЦЕНЦИЯ -- КРИСТАЛЛИЗАЦИЯ
Аннотация: Published data on aggregation kinetics of sodium chloride crystals at its spontaneous crystallization from supersaturated aqueous-ethanol solutions were analysed. It was found that the crystals coalesced through contact nucleus-bridges between them according to the mechanism proposed by Polak. The kinetics of aggregation were described by the Smoluchowski equation for coagulation of colloidal particles. The kinetic coefficient of aggregation process depended on supersaturation, temperature of solution and other characteristics of the system. The specific surface energy of sodium chloride 0.95 mJ/m2 was found

ВОЛЬФРАМАТСЕЛЕКТИВНЫЕ ЭЛЕКТРОДЫ -- СЕНСОРЫ
Аннотация: A chemical sensor for tungstate ions has been developed and implemented in two versions on the basis of the poorly soluble nickel(II) hexatungstonickelate(II) heteropoly compound. The electrode function is linear within the range 10–5–10–1 M tungsten for the film electrode and within the range 10–4–10–1 M tungsten for the coated wire electrode at pH 6–9. The slope of the electrode function is 28–29 mV. The time it takes to attain an equilibrium electrode potential is 1–5 min, depending on the ion concentration to be determined. The selectivity coefficients are found for the tungstate-selective electrode in the presence of chloride, sulfate, nitrate, and perchlorate
