ABSTRACT
One of the sources of clean water that is being used by humans is groundwater.
The community in Belading Village, Sabak Auh District, Siak Regency uses well
water which contains high iron (Fe) that need to be processed to reduce the Fe
metal itself by adsorption using activated charcoal. Corn cobs are one of the
potential agricultural wastes that used as activated charcoal. Corn cobs are
mostly composed of cellulose (41%), hemicellulose (36%), lignin (6%), and other
compounds that indicate a high enough carbon content. This study aims to
determine the effect of activator concentration and particle size of corn corbs
adsorbent on Fe metal removal in well water. Corn cobs were dried in the sun for
4 days and cut into 1 – 2 cm sizes. Corn cobs were carbonized at 500oC for 1
hour, followed by sieving with sizes of 60, 80, and 100 mesh. Activated corn cobs
with HCl 0,5; 0,75; 1; and 1,5 M. The adsorption process was carried out with a
stirring speed 0f 100 rpm and a contact time of 1 hour. Analysis of the FTIR
characterization of corn cobs showed the presence of activated charcoal
functional groups, O-H, C=O, C=C, and C-O. The results showed the highest
removal of Fe metal was 80,93% at a activator concentration of 1 M and a
particle size of 100 mesh and produced activated charcoal which had a water
content of 4,5%, ash content of 4%, volatile content 5%, absorption of iodine by
894,65 mg/g, and a surface area of 889,87 m2/gr.
