| Abstract | This paper concerns the removal of ammonium ions (NH4+) from aqueous solution using a hydrogel composite chitosan graftedpoly (acrylic acid)/rectoritepreparedfromin situ copolymerization. The effects of rectorite content, contact time, pH, NH4+ concentration and temperature on the adsorption capacity were discussed. Langmuir, Freundlich, Tempkin andRedlich–Peterson isothermswere usedto describe the experimental data. The results indicate that the adsorption equilibrium can be achieved within 3–5 min and, the hydrogel composite has a higher adsorption capacity for NH4+ in a wide pH levels ranged from 4.0 to 9.0.No significant changes in the adsorption capacity are found over the temperature range studied. The adsorption mechanism of NH4+ onto hydrogel composite was proposed, and the reusable ability of this hydrogel adsorbent was evaluated. |
