Abstract

177,180. Sauer, J. N. A. June 20. 1919. Carbon.-Decolorizing-carbon is revivified after use bv treatment with an acid other than sulphuric acid, followed by washing. For instance, it may be boiled for an hour or more with 2 per cent hydrochloric acid. When after several revivifications such a treatment fails to revivify. the carbon is subjected to a re-burning process of a known kind either before or after an acid treatment of the kind described: and where the reburning follows the acid treatment a second acid treatment may be applied after the burning.
