AB - Mg‐Al layered double hydroxides (Mg‐Al LDHs) were used as an adsorbent for hydrogen sulfide (H2S) removal. Removal efficiency of H2S by the Mg‐Al LDH has been investigated at different temperatures and humidity. The results have shown Mg‐Al LDH to be highly promising as an adsorbent for H2S removal. Research results about sorption mechanisms indicate that at lower temperatures (20 ºC), H2S removal by Mg‐Al LDHs is mainly a physical sorption process; however, at higher temperature (> 40 ºC), it is dominated by chemical reactions involving ion exchange. Confirmation of the redox reaction between H2S and Mg‐Al LDHs was provided by XPS data. The results obtained demonstrate that the H2S removal efficiency of Mg‐Al LDHs increases with the temperature increasing, and decreases with the water vapour content increasing.
