 1538.    ---------------.  [IIZIMA, S.]  [Adsorption of Hydrogen on Reduced Nickel.  Studies at Low Temperatures.]  Rev. Phys. Chem., Japan, vol. 12, 1938, pp. 1-14; Chem. Abs., vol. 32, 1938, p. 6124.

       Adsorption velocities were studied at 6 temperatures between –23° and –130°.  The adsorption occurring 1 min. after the start consists of several activated adsorptions with markedly different velocities.  The heat of activation of a particular adsorption was found to be 7,100 cal.  Adsorption isotherms for some particular adsorptions were found, which gave a heat of adsorption of 10,600 cal.
