    This research was performed to evaluate the recycling characteristics by physico-chemical analysis of wasted and regenerated activated carbons. Three types of waste carbons for gas treatment, drinking water purification, and wastewater treatment were sampled and analyzed. Heavy metals concentrations of As, Zn, Pb and Cd for all regenerated carbons satisfied the standard criteria of the granular activated carbon for drinking water purification. The sieve residues of the regenerated activated carbons for drinking water purification and wastewater treatment were in the range of 85.3∼97.7% and 97.7∼99.7%, respectively. Some samples of the regenerated activated carbons were not able to satisfy the standard criteria for methylene blue adsorption (150mL/g) and iodine adsorption (950mg/g). All activated carbons for gas treatment and drinking water purification satisfied the standard criteria for hardness and bulk density. One of three activated carbon samples for drinking water purification did not satisfied the standard criteria for phenol number and ABS (alkyl benzene sulfonate) number. The observed results concluded that there was no problem of heavy metals accumulation in the regenerated activated carbon, but partially against standard criteria such as sieve residue, moisture content, methylene blue adsorption, and iodine adsorption.
