Abstract
Arsenic is one of the major pollutants and a worldwide concern because of its toxicity and chronic effects on human health. The synthesis of copper containing modified cellulose (Cell-N-Cu) adsorbent was achieved. The adsorbent was used to purify different waters from As(V) at different experimental conditions using batch method. Kinetic and thermodynamic properties as well as the mechanism of interaction between As(V) and adsorbent active sites were discussed. The adsorption behavior of the obtained samples showed high adsorption capacity as well as fast kinetics towards As(V) in their solutions. The maximum adsorption capacities of As(V) on Cell-N-Cu adsorbent were found to be 1.32mmol/g. Regeneration and durability of the loaded adsorbent towards the successive reuse were also investigated. Fast and selective separation of As(V) from a real wastewater sample indicated that the investigated resin is potentially attractive for arsenic removal from different waste streams.
