Rice husks were a significant component of side product agriculture in the rice milling process. It is a classic environmental problem as a source of agricultural waste. To utilize cellulose as a major component in rice husk, there has been substantial study undertaken on the preparation of activated carbon as porous materials. Studies of porous activated carbon (PAC) show the importance of the application of porous materials such as adsorbents to remove environmental pollutants. This present research aimed to inquire the effect of carbonization temperature (600, 700, 800, and 900°C) with HCl as chemical activated solution. The PAC products were analyzed with the quality standard base on the national standard of Indonesia by number SNI 06-3730-1995. Analyzing the standard parameters of PAC were moisture content, ash content, volatile matter, fixed carbon, and the amount of iodine absorption capacity have been studied. The PAC products were characterized with FTIR and BET surface area analyzed to evaluate the porous of PAC. Returning to the initial inquiry of this investigation, it is now possible to state that carbonization temperature is at 700°C. The higher specific surface area (504,03 cm2/g), pore volume (0,258 nm), and micropore diameter (0,896 nm) have been analyzed by multipoint BET method. Based on quality standards analyzed, the moisture content (0,67%) and volatile matter (15,71%) to related for activated carbon from rice husk. A number of feasible future studies of activated carbon from the natural source using the same experimental setup are evident. [ABSTRACT FROM AUTHOR] |
