The study on equilibrium adsorption modeling of anions onto chelating fibers having amine groups under various pH |
| 초록 |
Chelating polymers have been well studied for the wastewater treatment. many scientists and engineers are therefore interested in developing these materials. Despite of this situation, the kinetic study of anion particles adsorption on a chelating fiber is still far from the real application due to describing chain motions of a polymer and uncertain ion concentration distribution. In this study, we presented a new adsorption modeling of anion particles onto a chelating fiber. These phenomena are described using the geometric factor of effective concentration. the anions adsorb on the chelating fiber H+ adsorption on this polymer. The concentration of H+ changes under various pH. After equilibrium of H+ adsorption on the chelating fiber, adsorption amounts of anions do not change. In this modeling, H+adsorption concentration on the chelating fiber was described using the Freundlich isotherm. The used chelating polymer was synthesized by coupling diethylene triamine to polyacrylonitrile (PAN) fiber tribology in the presence of the AlCl3. 6H2O addition.
