PENGARUH DAYA IRADIASI GELOMBANG MIKRO TERHADAP KUALITAS KARBON AKTIF CANGKANG BUAH KETAPANG SEBAGAI ADSORBEN ZAT WARNA
2016
Activated carbon had successfully been made from shell of Terminalia Catappa L prepared bycarbonization and KOH activation with microwave assisted process. The activation process wascarried out at irradiations times of 20 minutes with various power irradiation of 540 Watt, 630 Wattand 720 Watt. The physical properties of activated carbon were characterized by scanning electronmicroscopy, X-ray diffraction and methylene blue adsorption. The power of microwave irradiationof 630 Watt resulted the highest methylene blue absorption as high as 79,2688 mg/g.Microstructure analysis of the sample showed that the height of layers (Lc) was inverseproportional to its stack diameter (La) and interlayer distance was slightly affected d002 and d100 thepower of microwave irradiation.
