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 adsorption capability of dimethylglyoxime immobilized organobentonite (DMG-bentonite) for lead ion in water was investigated. The optimum experimental parameters for the adsorption and preconcentration of the lead ions, such as pH, time, eluent and coexisting ion, have been studied. The results showed that the lead ion in water could be adsorbed on the DMG-bentonite. The adsorbed quantitively was affected by the pH value of medium and contact time. In the medium of pH 5-8, the adsorption time was 10 min, and capacity of adsorption was 16.72 mg/g. The lead ion adsorbed on the sorbent could be completely evaluated by using 1 mol/L HNO3. The adsorption agent has been applied to the removal of the lead in the wastewater and the preconcentration of lead ion in surface water sample.
