94-0355 O2 Influence on Hydrogen Penetration Rate Through an Iron Membrane in Solutions of Different Anionic Nature. A cell with the verticai membrane of steel St3 was used it was found that the presence of oxygen had littie elfect on the hydrogen penetration rate (if in Fe in solutions with a pH = 3 A decrease in the I A n aetated soiullons was found with decreasing acidity of an electrolyte. It was the case both for electrostatic and potentiostatic conditions. Greater flux of oxygen (at PH 21 due to mixing also laded to raise the I With the addition of 10W4M H202, the I was 1 8 times as high as background. A sharp drop in the i with increasing pH of aerated solutions resulted from alkalization 01 areas close to the e'ec:rodes durrng reducing 0 7 . A critical value of pH at which theFe hydrogenation essentially ceased depended on the anionic composition of a solution. Graphs 13 ref.
