H2S adsorption characteristics of adsorbent made by fallen leaves were investigated. For analyses of the manufactured adsorbent, various methods such as scanning electron microscope(SEM) and measurements of BET surface area were adopted. As major adsorption characteristics, adsorption equilibrium capacity was measured by using a batch type experimental apparatus for operating variables such as adsorption temperature(25~45℃) and adsorbent types. The experimental result showed that the H2S adsorption equilibrium capacity of adsorbent made by fallen leaves decreased with increasing adsorption temperature due to physical adsorption phenomena. It was also found that the H2S adsorption capacity of the adsorbent increased remarkably by an acid treatment with HCl solution.
