    Abstract

    A graphite electrode at which Cl is evolved takes up Cl, this being the cause of a gradually decreasing Cl evolution after the current has been s witched off. From the fact that by immersion in alkali, O is evolved, it must be concluded that this Cl is present in at. form. Detn. of the amt. taken up as a function of electrode dimensions, temp., c.d., and the time it has been in use as an anode, leads to the conclusion that the at. Cl probably is adsorbed on the surface of the crystallites inside the graphite. Its diffusion coeff. is D = 2.4 * 10-3 exp (-4500/RT) cm2/sec. [on SciFinder (R)]
