Removal of Hydrogen Sulfide Gas Pollutants with Various Wet Banana Leaf Types

Hydrogen sulfide (H 2 S) gaseous pollutants are naturally generated from natural gas streams, organic waste degradation, and biogas production. Removal of the H 2 S pollutants is very important due to their harmful and odorous gas. In this study, the removal of this gas was carried out with a natura...

Description
Summary:Hydrogen sulfide (H 2 S) gaseous pollutants are naturally generated from natural gas streams, organic waste degradation, and biogas production. Removal of the H 2 S pollutants is very important due to their harmful and odorous gas. In this study, the removal of this gas was carried out with a natural biosorbent that is abundant in tropical countries, namely banana leaves. This study aimed to reduce H 2 S gas through the adsorption process using different types of banana leaves, specifically Kepok Putih, Raja Nangka, and Tonto. This study used adsorption tubes and measurements of H 2 S with a spectrophotometer and tested the characteristics of the leaves with SEM–EDX. The results showed that all tested banana leaves here performed removal of H 2 S gas, albeit at different levels. The H 2 S gas adsorption efficiency values for the Kepok Putih, Raja Nangka, and Tonto leaves were estimated to be 45.66%, 72.93%, and 59.08%, respectively. The best adsorbents were Raja Nangka banana leaves, which had an 11.0480 mg/g adsorption capacity. Based on this study’s results, it seems that leaf stomatal size determines adsorption capacity compared to moisture and surface area of the banana leaf. The abundance of this biosorbent in rural areas and ease of preparation make it feasible to be developed as a low-cost H 2 S biosorbent.
