Permittivity and Dielectric Relaxations in Liquid-Ammonia Solutions
ثبت نشده
چکیده
Dielectric constant and loss in liquid-ammonia solutions of alkali halides have been measured in the frequency range 0.7 — 70 GHz. At least one relaxation process exists in this frequency range in addition to the relaxation of the solvent molecules. The additional relaxation is ascribed to the orientational polarisation of ion pairs. The concentration of the ion pairs, calculated with a special model, is 30 — 50% of the total concentration. The interaction between ions and solvent molecules is discussed.

Microwave cavity perturbation studies on H-form and ion- exchanged SCR catalyst materials: correlation of ammonia storage and dielectric properties
Ammonia-based selective catalytic reduction (SCR) has become the major control strategy for NOx emissions from light and heavy duty diesel engines. Before reducing NOx on the SCR active material, ammonia storage on the active sites of the catalyst is crucial. The in operando measurement of the dielectric properties of the catalyst material using microwave cavity perturbation is a promising indi...

In this work, reactive absorption of gases in aqueous electrolyte solutions has been investigated resulting in the development of a procedure in order to calculate the concentrations of ionic and molecular species in the liquid phase. Two duplicate experiments were conducted to investigate simultaneous reactive absorption of ammonia and carbon dioxide in partially carbonated ammonia solutio...
متن کاملA Dielectric Spectrometer for Liquid Using the Electromagnetic Induction Method
Dielectric spectroscopy is useful for the characterization of colloidal dispersions. In the past, dielectric spectroscopy has been attempted using parallel metal electrodes to measure the permittivity and conductivity of colloids. However, it is difficult in practice to make these measurements in conductive solutions because large measurement errors can be caused by electrode polarization, whic...
متن کاملA broad spectrum analysis of the dielectric properties of poly(2-hydroxyethyl methacrylate)
The dielectric permittivity, 3 0, and the loss factor, 3 00, of dry poly(2-hydroxyethyl methacrylate) were measured using a dielectric analyzer in the frequency range of 0.1 Hz to 100 kHz and between the temperature range of K150 to 275 8C. The dielectric response of the sub-Tg g transition of PHEMA has been widely studied before but little to no DEA data above 50 8C is present in the literatur...
متن کاملModeling of dielectric properties of complex fluids with an equation of state.
The static permittivity is a key property for describing solutions containing polar and hydrogen bonding compounds. However, the precise relationship between the molecular and dielectric properties is not well-established. Here we show that the relative permittivity at zero frequency (static permittivity) can be modeled simultaneously with thermodynamic properties. The static permittivity is ca...
