PENGARUH WAKTU AKTIVASI KIMIA PADA KARBON AKTIF BERBAHAN DASAR ARANG ROTAN SERTA KARAKTERISASI MENGGUNAKAN SEM DAN FTIR

Abstract

Activation of rattan charcoal is carried out to increase pore size and form
functional groups. In this study, activated carbon from rattan has been made with
different activation times. The research objective was to determine the pore size and
functional groups contained in the activated carbon of rattan with an activation time of 5
hours and 10 hours. The solution used to activate rattan activated carbon is KOH 10 ml
charcoal 10 grams with a burning temperature of 1500C. The results of rattan activated
carbon were characterized using SEM and FTIR to see the pore size and functional
groups. The activated carbon sample of rattan with the activation time of 5 hours had a
pore size that was not too large and only a few were formed and the sample of 10 hours
of activation time had a large pore size. The samples for 5 hours and 10 hours of
activation have the same functional groups, namely O-H, C-C, C-O, C-H.
