Abstract:
Orange peel based activated carbon by microwave assisted potassium hydroxide
chemical activation has succesfully been made. Pre-carbonized of activated carbon
was conducted for 1 hour at temperature of 150˚C and followed by chemical
activation using KOH with variation of molarity of 2 M, 3 M, and 4 M. The
microwave pyrolisis was carried out using output power of 630 Watt for 15 minutes.
The molarity of KOH was influenced by of the physical properties of activated
carbon. Higher of output of activator concentration shows bigger of carbon content
produced. The data of energi dispersive X-ray show the activated carbon of KJ4M
has the highest of carbon content of 66,55%
