Cellulose nanocomposite bead modified with metal (MCNB) such as Ce, Al and Fe is synthesized for selective adsorption of
arsenate anions As(V) from drinking water in batch system. The adsorbent was characterized by FTIR, FESEM, EDS and
EPR studies. In the present report arsenic(V) adsorption performance on cerium modified cellulose bead was described. The
maximum adsorption of As(V) is near about 100 percent up to an initial arsenic load of 5.0 mg L-1 at the acidic pH of 3.0 and
the equilibrium is reached in 5 h. The much higher adsorption extent and quick equilibrium time compared to the other
reported adsorbents makes the present adsorbent as efficient one. Among the three adsorption isotherm models used,
Langmuir model fitted the experimental data best. The adsorption is found to be exothermic, spontaneous and random in
nature. The process was applied for removal of arsenic from some real sample.
Key words: Metal loaded cellulose nanocomposite bead; batch study; arsenic adsorption; isotherm; water analysis.
