Popis:	International audience; With the expansion of human activities, there are more and more living areasadjacent to industrial and/or agricultural activities such as chemical processes, petroleumprocesses, paint finishing, food processing, livestock farming, composting plants etc. Badodor is part of several nuisances caused by industrial and/or agricultural activities. Hydrogensulfide (H2S) is a typical odorous molecule which causes foul odor at very low concentration.This molecule is formed in different industrial installations, in particular in coal combustion,and petrochemical refinery. The separation and/or transformation of H2S from gas phase toodorless products are important processes for sustainable development.In this paper, we communicate the preparation of new sorbents for the sorption of H2Sfrom a synthetic gas effluent. These sorbents consist in an inorganic phase (hydroxyapatite) ashost particles, and well-dispersed particles of a metal oxide as guest particles which are theactive phase for the removal of H2S. At room conditions, iron, lead and zinc doped calciumphosphates were found to be effective for the removal of H2S. The performance of thesorbents depends on preparation method and the nature of active phases. This opens newprospects for the treatment of H2S from gas phase.
