Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
An investigation was conducted on the adsorption and desorption of three basic amino acids (L-His, L-Lys and L-Arg) with a spherical cellulose adsorbent containing the carboxyl group. Static experiments were carried out as function of pH, initial amino acid concentration, adsorption time and temperature. The adsorbent showed excellent adsorption capacities for the mentioned basic amino acids. The equilibrium adsorption data of the amino acids on adsorbent were analyzed by Langmuir and Freundlich models. The kinetics of basic amino acids adsorption nicely followed the second-order rate expression which demonstrated that chemical adsorption plays a significant role in the adsorption mechanism. Moreover, dynamic experiments were performed to determine the breakthrough curves. Regeneration experiments were tried four cycles and the results implied that the cellulose adsorbents had such advantages as simple regeneration, high recovery and reusability.
