Stratified Dipole‐Arrays Model Accounting for Bulk Properties Specific to Perfluoroalkyl Compounds

“…Because the ÀCF 3 group is chemically connected to the À(CF 2 ) n À group, the situation can roughly be approximated to be CF 4 , which is insoluble in water, [13] through similar logic to that used for CCl 4 . As a result, the surface of the 2D aggregate of the R f groups should exhibit a hydrophobic or very weak hydrophilic character.…”

Radon, helium and CO2 measurements in soils overlying a former exploited oilfield, Pechelbronn district, Bas-Rhin, France

“…Due to various dissolution properties, evaluating soil water contents is one important parameter, especially for CO 2 and 222 Rn. At 25 C and 1 bar, the respective mole fraction solubilities are 64.48 and 16.75 and only 0.70797 for helium (Scharlin et al, 1998). Nevertheless, no soil humidity quantification was associated with this study initiated by the regional health authorities.…”

“…Figures 7 and 8 show the comparison between observed and calculated contents for He, Ne, N 2 , methane, ethane, and propane, and the comparison between observed and calculated pressure. Hydrogen and CO 2 contents evolve independently from the other dissolved gases (Vinsot et al 2008Cailteau et al 2011a); hydrogen evolution involves consumption processes, whereas CO 2 content is controlled by reactions with rock minerals and the ceramic screen in the case of The solubilities (Scharlin et al 1998) and diffusion coefficients in pure water (D w ) are for 25°C; value for HTO in water comes from Mills and Harris (1976); values for the gases N 2 , Ar, CH 4 and CO 2 were taken from Table 4.4 in Boudreau (1997) and stem from Jähne et al (1987) and Ohsumi and Horibe (1984). Values for the gases C 2 H 6 and C 3 H 8 come from Hayduk and Laudie (1974) and (Table 4.3 in Boudreau 1997), but multiplied by 1.1 to be commensurate with the higher diffusion coefficient for CH 4 given by Jähne et al (1987) compared with Hayduk and Laudie (1974); in the model, solubilities are corrected to 15.6°C using Van't Hoff's equation with the dissolution reaction enthalpy (DHr) or with a polynomial; effective diffusion coefficients (D e ) are corrected by accounting for the viscosity change of water with temperature at 15.6°C BHT-1.…”
