STAINLESS STEEL WASTES: Ⅲ. LABORATORY STUDIES OF THE RATE OF REMOVAL OF STAINLESS STEEL IONS BY MERCURY CATHODE ELECTROLYSIS

摘要

The reported experiments studied the removal rates of iron, nickel, and chromium from synthetic stainless steel waste solutions during electrolysis over a mercury cathode. The loading capacity of the mercury for the stainless steel metals is estimated on the "basis of laboratory experiments to he about two per cent by weight. The laboratory data indicate that, at an electrode potential of -1.80 volts vs S. C. E., 85 ampere-hours per liter of waste removed essentially all of the stainless steel ions from a sulfuric acid solution containing 0.13M metal ions at 35°C.
