Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
The technological conditions of absorption of H2S using pyrolusite ferric sulfate were studied. In this process, low cost raw materials are used, oxidation absorption of H2S and regeneration of ferric salt were realized simultaneously, and continuous operation can be achieved. Consequently, appropriate operating conditions were established: Room temperature; Concentration of sulfuric acid is 0.5 mol/L; Ferric concentration is 1.0 mol/L; Concentration of MnO2 is 3.0g /50mL. Under these conditions, the maximal ratio of absorption of 99.2% can be achieved in discontinuous operation process, and approximately 100% absorption of H2S can be achieved by multi-absorption in series and addition of pyrolusite and sulfuric acid in continuous operation process.
