Preparation, Characterization and Application for LeadAdsorption of Dendrocalamus Asper Backer BambooActivated Carbon

Abstract

     The objectives of this research ware to prepare and characterize Dendrocalamus Asper Backer bamboo activated carbon and to investigate the lead removal efficiency. The effects of activators as phosphoric acid (H3PO) and potassium hydroxide (KOH) by using heating methods as reflux and microwave radiation, initial concentration of lead(II) ions, and adsorbent dosage were examined. In addition, functional group characterization of the prepared adsorbent was performed by using 4 Fourier Transform Infrared Spectroscopy (FTIR). The optimized condition for prepared activated carbon was heated with microwave radiation for 10 minutes. Under this condition, the highest iodine was release at the highest level of 1,265 mg/g indicating the highest adsorption capacity. Moreover, the maximum lead ions adsorption was obtained at activated carbon dosage of 0.25 g with a contact
time of 8 minutes and concentration of 10 ppm lead illustrated the appropriate conditions for lead removal efficiency by adsorption.
