Pembuatan Karbon Aktif Dari Kayu Randu dan Tempurung Kelapa Dengan Proses Distilasi Kering Menggunakan Tanur dari Gerabah
ABSTRACT: Preparation of
activated carbon from silk cotton wood and coconut shell has been done. Carbon
was made by pyrolysis process in the Muchalal furnace with 3000 watt electric
power. The electric power was increased gradually from 1000, 2000 and then 3000
watt with interval 2 hours during 7 hours. Carbon was activated in Muchalal
furnace with 4000 watt electric power during 2 hours and flowed with nitrogen
gas. Product of the activated carbon was compared to standart product with
several analysis including the surface area, acetic acid adsorption, iod
adsorption and vapour adsorption. The results of analysis showed that surface
area for silk cotton wood carbon, coconut shell carbon, and E.Merck product
were 288.8072 m2/g, 222.9387 m2/g and 610.5543 m2/g, respectively. Acetic acid
adsorption for silk cotton wood carbon, coconut shell carbon, and standart
product were 157.391 mg/g, 132.791 mg/g, and 186.911 mg/g, respectively. Iodine
adsorption for cotton wood carbon, coconut shell carbon, and standart product
were 251.685 mg/g, 207.270 mg/g and 310.905 mg/g, respectively. Vapour
adsorption for cotton wood carbon, coconut shell carbon and standart product
were 12%, 4%,and 14%., respectively
