If a gas with high concentration of H2S (30,000 ppm) has been placed in a 500 cc cylinder for one month, how much of sulfur compounds (such as H2S) are adsorbed by titanium or titanium sulfinert coated surface (1% or more)? Can you introduce me any document about adsorption of sulfur compounds on titanium or stainless steel surface? How much of H2S concentration is adsorbed to passivate surface of titanium or stainless steel?

I would use a thin titanium/stainless steel sheet or wire. Deposit it, then dissolve (microwave digester) and analyse for sulfur using ICP-methods. Take into account the surface of your sample.
