“…Within experimental accuracy no noticeable differences in the with-field and no-field isotherms were observed. This confirms the hypothesis (Panasyuk et al, 1978) that, for strongly adsorbing surfaces such as silica gel, the equilibrium adsorptive forces are much stronger than the ponderomotive forces.…”

“…The adsorption kinetics of nonpolar ethylene tetrachloride on silica gel S-2509 at 25 °C, p/pQ ~= 1, is shown in Figure 8. As observed by Panasyuk et al (1978) in the case of CC14, the adsorption behavior of nonpolar adsorbates seems to be unaffected by applied electric fields. Panchenko et al (1973Panchenko et al ( , 1972 have suggested that the enhancement of adsorption kinetics in porous media is only possible in nonuniform applied fields and that uniform applied fields produce no effect.…”

“…In this section quantitative estimates of (V/u7)z°a nd (V^7)zp will be obtained and compared in an attempt to explain the various experimental observations. Prior to our work previous authors (Karpovich et al, 1981;Panasyuk et al, 1978) have invariably attempted to explain the enhanced adsorption kinetics by the formal expansions of (Vjut)jp in the gas phase and/or the adsorbate phase.…”

“…Adsorption of polar and nonpolar vapors on dielectric adsorbent surfaces in the presence of electrostatic fields has been relatively ignored, except for the work of one or two Russian research groups. Some of the works of the first group, viz., Panchenko et al (1972) and Panasyuk et al (1978), have been translated into the English language. The works of the second group (Kuliev et al, 1974(Kuliev et al, ,1978 are available only in Russian (except for the summaries available in Chemical Abstracts).…”

Experimental investigations of the effects of electric fields on the adsorption of water vapor on silica gel and alundum catalyst were carried out at 25 °C. The presence of a nonuniform field surrounding the solid particles causes an increase in the rate of adsorption but not the amount absorbed. Presence of alkali metal ions in silica gel has a strong effect. In the absence of these ions field strengths smaller than about 5 X 104 V/cm have little effect. Theoretical analysis of the phenomena indicates that it Is important to compute the local, internal electric fields in the pores rather than the external applied fields.

Excess moisture in a building is a serious problem that affects the quality of life and the durability of construction. The usage of electro osmosis in historic buildings has longer data as it is the least destructive method for removing noxious moisture from masonries. Beneficial effects of electro osmosis on the moisture elimination have been documented in various scholarly articles and works. Wireless electro osmosis, based on the influence of magnetic or electromagnetic field on the water cumulated in masonries is often questioned because of the lack of scholarly works focused on the physical principles of the method. Results from our own tests were confronted with the theoretical background.
