Abstract
This work characterized the microstructure of stainless steel before and after adsorption. At the same time, the adsorption experiments at different temperatures and the adsorption characteristic experiment were carried out. The results show that chemical adsorption has taken place on the surface of stainless steel. The change of temperature has little effect on the functional groups of the stainless-steel surface after adsorption. Hydrogen sulfide showed the largest adsorption capacity and fastest rate, while methyl and ethyl mercaptan performed second. Carbonyl sulfide exhibited the smallest adsorption capacity and slowest rate.
