Effects of Pollutants and Micro-Organisms on the Absorption of Electrolytic Hydrogen in Iron
Abstract
The objective of this research is to define conditions under which pollutants, in particular those produced by bacteria such as sulfide end products of the SRB, affect the amount of hydrogen absorbed by iron/steel. In this current year of the project, our research focused on three related thrusts which will be reported separately below: (1) The effect of thiosulfate, which is a source of H2S as well as other sulfur forms on hydrogen absorption into steel, (2) Modification of the IPZ analysis to include Frumkin interaction effects in order to obtain a quantitative determination of the effect of H2S on hydrogen absorption into steels, and (3) The development and testing of an analytical procedure which requires only the readily obtainable polarization data to quantitatively characterize the HER in the same way the IPZ analysis does, but much more simply and with far less sophisticated equipment. The technique is also applicable to some other metals beside iron and steels, including nickel, stainless steel, and Cu.
