“…Konsentrasi H2SO4 mempengaruhi karbon aktif yang terbentuk. Menurut Jia Guo [10] dengan meningkatnya konsentrasi H2SO4 akan meningkatkan hasil dari BET surface area sampai dengan konsentrasi 30% (≈6M), dan menurun jika konsentrasi ditingkatkan.…”

This research studied to utilize the bagasse to be used as activated karbon in particular for the adsorption of Ca 2+ . The manufacture of activated carbon consists of carbonization dan activation process. Temperature variation for carbonization process in this research are 500°C, 550°C, 600°C, 650°C and 700°C then proceed with the activation process by carbon reflux with 6 M H2SO4 for 4 hours. Carbonization yield will decrease with increasing temperature carbonization. While the ash content, surface area, pore volume, and adsorption capacity of Ca 2+ will increase with increasing temperature of carbonization. Obtained activated carbon is best activated karbon made at a temperature of 700°C with an activation carbonization which has a surface area 100.62 m 2 /g, 22.3750 Å pore diameter, pore volume of 22.376 mL/g, can eliminate the Ca 2+ up to 13.26 %.

“…[7][8][9][10][11][12][13][14][15][16][17][18][19] The charcoal carbonized from 400 to 500°C is found effective for the adsorption of basic ammonia gas due to many acidic functional groups on its surface. [7][8][9][10][11] It is also described that the adsorption amount of the ammonia gas on activated carbon increases by modifying the acidic functional groups on the surface of the activated carbon with an oxidizing reagent.…”

The effect of ammonia adsorption in aqueous solutions was examined for bamboo charcoal carbonized at 400, 700 and 1000°C, and activated carbon. Furthermore, the change of the ammonia adsorption in aqueous solutions was also examined by treatment of each sample with diluted sulfuric acid. Bamboo charcoal carbonized at 400°C and treated with diluted sulfuric acid was the most effective for removing ammonia from aqueous solutions. Although the ammonia adsorption of the bamboo charcoal carbonized at 400°C in gas phase hardly changed by the treatment with diluted sulfuric acid, that in aqueous solutions significantly increased by the treatment.

“…This limited the application of activated carbon in ammonia removal as the key factor that dominates the ammonia adsorption capacity of the activated carbon is the surface chemistry, especially the acidic groups [8]. The chemical properties of the carbon surface, especially acidic functional groups, have a strong influence on NH 3 adsorption [17]. The impregnation of H 3 PO 4 on the activated carbon induces acidic groups at the basal planets of the activated carbon, and thus, creates more active sites on the activated carbon surface.…”

To accommodate long duration biology research with rodent habitats on the International Space Station while providing a healthy living and working environment for crewmembers, NASA Ames Research Center developed a new exhaust filter for odor control for the Animal Enclosure Module (AEM), which houses mice and rats. The new exhaust filter uses activated carbon pellets as adsorbents, with phosphoric acid (H 3 PO 4 ) impregnated on the surface. The deodorization performance of the new exhaust filters for AEM units housed with mice was evaluated. The ammonia breakthrough time of the exhaust filters was also investigated. The results indicated that H 3 PO 4 treated activated carbon exhibited a high ammonia adsorption capacity of more than 90%. Furthermore, the new exhaust filter can effectively control the odor from the AEM units for a 45-day (minimum) flight mission with a given animal biomass.
