The Ferrox process is one of the wet processes for removing hydrogen sulfide from crude gases, and it is based on the following reactions, that is, the absorption of hydrogen sulfide with an aqueous suspension of ferric hydroxide, and the removal of sulfur from iron sulfide by an oxidation with air.　2Fe(OH)_3 + 3H_2S = Fe_2S_3 + 6H_2O　2Fe_2S_3 + 3O_2 + 6H_2O = 4Fe(OH)_3 + 6S　In practice, however, the removal of hydrogen sulfide by this process has not always been satisfactory, and the regeneration of the absorption liquor has not so easily accomplished.　The authors made the following studies both fundamental and industrial with the object of improving the process by eliminating the above disadvantages.　... Part 2; Study of industrial chemistry on the Ferrox process.　Under the following conditions the studies of the absorption of hydrogen sulfide with various absorption liquors were made.　(1) The comparison of the absorption capacity of the freshly prepared absorption liquors (alkaline and neutral.)　(2) The absorption of hydrogen sulfide with the absorption liquor containing varying amounts of sodium carbonate or sodium bicarbonate.　(3) The absorption of hydrogen sulfide from the gases containing carbon dioxide.　(4) The change of the absorption capacity after repeating of the removal and the regeneration.　(5) The absorption of hydrogen sulfide from the gases of the lower concentration of hydrogen sulfide.　(6) The absorption of hydrogen sulfide from the gases containing hydrogen cyanide.　(7) The microscopical observation of the regenerated liquors.
