Hydrogen diffusion through a steel membrane in the acidic water–ethylene glycol solutions containing pyridine in conditions of the cathodic polarization

“…Such an absence of correlation between two functions of i c = f(E c ) and i H = f(E c ) contradicts to literature data [3,4]. However qualitative similar results are observed in the presence of As (V) compounds [12] and thiocarbamide (NH 2 ) 2 CS [13].…”

“…q = 0 (hydrogenation is absent). 2. q = 1 (the forming of H 2 according to (2) or (3) At the certain conditions the i 3 rate is determined by a surface diffusion of H ads what was watched, particularly, in [8,9]. Then the value of i H is not a function of the hydrogen diffusion coefficient through the metal and the kinetics of the H ads fit.…”

“…And with it, the nature and the solvent composition can influence considerably on the form of such dependences because of a change of the relative adsorptive ability of H atoms and the molecules of the non-aqueous component in the conditions of their competition because of the surface active centers of the metal. Moreover, in such media both the solvated form of the proton and its discharge kinetics change [12][13][14].…”

Hydrogen diffusion through the steel membrane in conditions of its anodic polarization

“…It does not connect with the pH value, the anion solution composition, the solvent nature and a character of the volume and surface solvation, a presence or an absence of the hydrogenation stimulators (HS). The last is proved by the results obtained in the C 2 H 4 (OH) 2 -H 2 O-HCl background solutions [19]. An absence of the influence of the solvent nature, the hydrogenation stimulators are sufficiently confirmed by the results obtained in the ethanol HCl solutions including in the presence of thiocyanate ions as the effective HS [20].…”

Effect of the structure of o,o´-dihydroxyazo compounds on bactericidal and inhibitory ability

“…This film often has certain protective properties and leads to a significant decrease in corrosion rate [18][19][20][21][22]. This effect becomes stronger in the presence of an inhibitor [23][24][25]. In the presence of SRB it has been shown that "there is no indication for significant catalytic enhancement of the abiotic cathodic proton reduction to hydrogen by deposited ferrous sulfide crusts" [11].…”
