| Abstract: | Adsorption properties of ammonia nitrogen in water onto metal ion-loaded resins were described. The adsorption isotherms of ammonia nitrogen over metal ion-loaded resins were measured. Increasing adsorption temperature enhanced the adsorption of metal ion-loaded resins. Metal ion-loaded resins adsorption behaviors could be well described using the Langmuir adsorption model. The kinetics of metal ion-loaded resins adsorption onto the metal ion-loaded resins could be well described by second order kinetics. |
