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.
The feasibility of tea industry-waste used for the biosorption of cadmium (Cd) ions from aqueous solution was studied. Batch experiments were carried out to evaluate the effect of some factors such as pH, contact time on the biosorption of Cd onto tea industry-waste. The maximum biosorption capacity was found at pH 7. Biosorption was rapid and three hour was selected as the optimum contact time. Biosorption of Cd increased with the decreasing size fraction of tea industry-waste. The kinetics was satisfactorily described by pseudo-first order and pseudo-second order model. Tea industry-waste is a better biosorbent for cadmium removal compared to some other biomaterials reported in the literature.
