In order to obtain the chelating fiber for adsorbing metal ions in apple juice, the effect of different conditions on adsorption properties of chelating fiber for Cu(II) ion were discussed, such as pH and the time of adsorption. The isotherm of adsorption has bee confirmed. The desorption and its regeneration were simply discussed, too. The results showed that the chelating fiber had good kinetic property and the adsorbed equilibrium completed almost within 20-30min. The adsorption properties was affected by the temperature and pH. The adsorption process fits the isothermal equation of Freundlich. The chelating fiber could be used repeatedly.
