An oil palm empty fruit bunch-derived activated carbon has been successfully produced by chemical activation with zinc chloride and without chemical activation. The preparation was conducted in the tube furnace at 500oC for 1 h. The surface structure and active sites of activated carbons were characterized by means of Fourier transform infrared spectrometry and field emission scanning electron microscopy. The proximate analysis including moisture content, ash content, bulk density, pH, and pH at zero charge was conducted to identify the psychochemical properties of the adsorbent. The results showed that the zinc chloride-activated carbon has better characteristics compared to the carbon without chemical activation.

The study of exhaust H2S and NO2 gases using activated carbon has been conducted. In this study, activated carbon was prepared from mendong plant (Frimbistylis umbellaris), which was activated using zinc chloride (ZnCl2) with concentrations of 2.5; 5; 7.5; and 10 % w/v to determine the efficiency of H2S adsorption. Mendong charcoal was obtained from the process of using a modified tool. Activation was done by maceration using ZnCl2 activator (w/v) for 24 hours. The adsorption of H2S and NO2 was analyzed using UV-Vis spectrophotometry. Determinations of H2S gas carried out using the blue methylene’s method for 1 hour showed the highest effectiveness of mendong activated carbon was of that at the concentration of 2.5 % ZnCl2 w/v with 80% of H2S removal. Further, the mendong activated carbon with the concentration of 2.5% ZnCl2 w/v was used for NO2 adsorption. The adsorption of NO2 gas was conducted for 1 hour using Griess Saltzman’s method. The result showed that the largest concentration of NO2 gas was adsorbed when the HNO3 concentration was 1.5 M (0.057 µg/mL). The percentage of NO2 efficiency adsorbed was at 28%.
