· Journal of Physical Chemistry (U.S.)
The course of absorption of deuterium by palladium wire specimens was followed by changes in their electrode potentials and relative resistances in dilute acid solutions. The electrode potential (25 deg , 1 atm D/sub 2/, W.R.T. Pt/D/sub 2/) in the region of coexistence of the alpha and beta phases is 31.0 plus or minus 0.5 mv as compared to 50 mv for the palladium--hydrogen system. The rate is constant over the majority of the absorption. An absorption isotherm was constructed from the change of electrode potential with deuterium content of the palladium. The temperature coefficient of the electrode potential was determined in the two-phase region, from which the heat of absorption is calculated as --8795 cal/mole D/sub 2/. (auth)
