Abstract

In this study, the feasibility of using waste concrete as a cover material to remove hydrogen sulfide (H₂S) from landfill gas was evaluated. The waste concrete composed of alkaline earth metal-based compounds was applied as a H₂S adsorbent owing to its high ion exchange capacity. The H₂S adsorption amount and breakthrough characteristics with relation to the temperature of the waste concrete and the flow rate of H₂S were examined by applying the Adam–Bohart, Tomas, and Yoon–Nelson models. The highest adsorption amount of H₂S per unit mass of waste concrete was achieved at 40 o C with a flow rate of H₂S of 100 mL/min. The Tomas and Yoon–Nelson models showed an R of 0.9601. A basic study was conducted on the H²₂S adsorption by waste concrete as the cover material.
