PENGARUH WAKTU KARBONISASI TERHADAP SIFAT FISIS KARBON AKTIF KAYU EUCALYPTUS PELLITA

Abstract

Activated carbon has been successfully made from wood Eucalyptus pellita with different carbonization time. Eucalyptus pellita wood carbonized conventionally using canned, cut and sieved to the size of 1-2 mm. Carbon with different carbonization time has been activated using KOH in ratio mass : KOH 2:1 and irradiated using microwave for 20 minutes at 630 watts. The research result showed carbon with highest percentage of sample KA 1,5 with a value 76,05% and followed sample KA 2,0 and KA 1,0 with a value 69,84% and 66,36%. Characterization testing was done to see the surface morphplogy, microstructure and absorption with using Scanning Electron Microscopy (SEM),X-Ray Difraction (XRD) and methylene blue. SEM micrograph data showed morphology and pores activated carbon. XRD data showed the distance between the lattice (dhkl), the width of the lattice (La) and high of lattice (Lc) with a value highest Lc KA 1,5 with value dhkl 3,99 nm, La 1,018 and Lc 3,035. Methylene blue data showed absorption capability and surface area activated carbon contained in KA 1,5 with a value 98,98 mg/gr.
