ABSTRACT

In this study, highly porous activated carbon was produced from rice straw by carbonization and followed by activation using potassium hydroxide (KOH). Activated carbon samples were prepared under different activation temperatures, i.e., 650, 750 and 850°C, and their physical and chemical properties were characterized accordingly. The BET surface area of the activated carbon samples was increased from 520 to 1048 m2/g with the increase of activation temperature from 650 to 850°C. These values were much higher than the non-activated rice straw carbon i.e., 1.16 m2/g. The pore sizes of the rice straw activated carbon were found to be mainly in mesopore size range of 2-50 nm. Total carbon content of the AC sample was increased from 8.35% to 31.73% with the increase of activation temperature from 650 to 850°C. XRD and Raman spectroscopy confirmed the graphite properties of the activated carbons produced. SEM images proved high porosity of the AC after KOH activation.

Keywords: Activated carbon; biomass; lignocellulosic

ABSTRAK

Dalam kajian ini, karbon teraktif berliang tinggi telah dihasilkan daripada jerami padi melalui proses pengkarbonan dan diikuti dengan pengaktifan bersama kalium hidroksida (KOH). Sampel karbon teraktif disediakan pada suhu pengaktifan yang berbeza, iaitu 650, 750 dan 850°C dan sifat fizikal dan kimia sampel tersebut dicirikan. Luas permukaan sampel arang teraktif meningkat daripada 520 ke 1048 m2/g dengan peningkatan suhu pengaktifan daripada 650 ke 850°C. Nilai ini adalah jauh lebih tinggi berbanding sampel karbon jerami padi tanpa melalui proses pengaktifan, iaitu 1.16 m2/g. Saiz liang karbon teraktif adalah pada saiz liang meso, iaitu dalam julat saiz 2-50 nm. Kandungan karbon bagi sampel arang teraktif telah meningkat daripada 8.35% kepada 31.73% dengan peningkatan suhu pengaktifan daripada 650 kepada 850°C. Analisis XRD dan spektroskopi Raman telah membuktikan sifat grafit karbon teraktif yang terhasil. Imej SEM membuktikan sifat keliangan yang tinggi bagi karbon teraktif jerami padi selepas proses pengaktifan KOH.

Kata kunci: Biojisim; karbon teraktif; lignoselulosa
