dc.description.abstract |
research has been conducted on activated carbon of Eucalyptus pellita wood
with various ratios of charcoal and potassium hydroxide of 1:0.25, 1:0.5, and
1:0.75 respectively. Chemical activation was conducted using the potassium
hydroxide for 20 hours and microwave irradiation with output power of 630 Watt
for 20 minutes. The aim of this research is to know the effects of potassium
hydroxide on the physical properties of activated carbon i.e yield of activated
carbon, micro structures, surface morfology, elements of activated carbon, and
methylene blue adsorption. X-ray diffraction patterns of the activated carbon
showed semicrystalline structure and SEM images showed porous activated
carbon. Weigh percentages of carbon (C), oxygen (O), and potassium (K)
elements of activated carbon were 67.87%, 30.63%, and 1.50%, respectively.
Adsorptive power of activated carbon on methylene blue was 97.45 mg/g and
surface area was 361.67 m2/g respectively |
