Adsorption Characteristics of Copper Ions and 2,4-Dichlorophenoxyacetic Acid onto CAC Bead |
| 초록 |
Adsorption characteristics of copper ions and 2,4-dichlorophenoxyacetic acid onto CAC beads were investgated. The average molecular weight and the degree of deacetylation of the chitosan used in this study were found to be 8.2 ×105 and 85%, respectively. The chitosan solution was prepared by dissolving chitosan powder into 2wt% aqueous acetic acid solution. And than CAC beads were made by mixing the chitosan solution and different amounts of powdered activated carbon. Sodium hydroxide solution was used as a gelation agent. Single component isotherms of copper ions and 2,4-dichlorophenoxyacetic acid onto CAC beads could be represented by sips isotherm. Adsorption capacity of copper ions increased with decreasing amount of activated carbon in the CAC beads. And that of 2,4-dichlorophenoxyacetic acid increased with increasing amount of activated carbon in the CAC beads. |
