Copper Removing from Contaminated Water Using Biochar Derived from Corncobs
Keywords:
Biochar, Copper, AbsorptionAbstract
The aim of this research is to remove copper ion from water by bio- char. The biochar were prepared by pyrolysis process using corncob and fired at 850oC in low oxygen atmosphere. The biochar were characterized by SEM, EDS and XRD. The results showed graphite and carbon crystalline and pore size about 10-15 m. The biochars were crushed by hammer mill and separate size by sieve for 3 ranges (105-149, 149-177 and 177-210
m) and dipped in the copper solution for 5-60 minute. The saturated copper absorption times of all size were about 15 minute. The maximum absorp- tion rate is 0.8 mg/gmin by the size range 105-149
m.
