| Abstract: | Series of rice husk based active carbon(AC) was prepared by chemical activation with NaOH and H3PO4 as activator.These obtained ACs were applied for adsorption of heavy metals in solution,their difference in adsorption of Cd,Cu and Zn were compared.The specific surface area,methylene blue adsorption value,iodine adsorption value,phenol adsorption value and pHpzc of the prepared ACs were determined,and the crystal structure of ACs was also analyzed by an X-ray diffraction.Results showed when NaOH was used as... |
