In order to improve their efficiency for the removal of H2S contained in polluted effluents, activated carbon fibres are impregnated by KOH aqueous solutions. In presence of water vapour, H2S is not simply physically adsorbed on the surface of the treated cloths but several reactions can occur. The fixation mechanism proposed has been validated and completed through the calorimetric study of the heat effects induced by the reactions that occur when the treated fibres are in contact with a gas mixture of H2O and H2S.
