Efficient and Fast Adsorption of Phosphates and Sulphates on Prepared Modified Cellulose

Abstract

Synthesis of modified cellulose (Cell-GTA) containing quaternary amine functionality was performed. The adsorbent was used to adsorb phosphate and sulphate anions at different experimental conditions using batch method. Kinetic and thermodynamic properties as well as the mechanism of interaction between studied anions and adsorbent were discussed. The adsorption behavior of the obtained samples showed high adsorption capacity as well as fast uptake toward studied anions in their solutions. The maximum adsorption capacities of and on Cell-GTA were found to be 1.88 and 3.68 mmol/g, respectively. Regeneration of the loaded adsorbents toward the successive reuse was also investigated.
