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.
In order to evaluate the effects of heavy metals discharged in the environment water, a novel method using a glass column packed with chicken eggshell membrane (ESM) as a new adsorption material was developed for the preconcentration of trace Pb in environmental water sample prior to its determination by atomic absorption spectrometry (AAS). The adsorption behaviors of the analytes on ESM under dynamic conditions were studied systematically. It was found the ESM is an effective solid phase extractant for the adsorption of trace cadmum at pH range of 5.5-7.5. Under the optimized conditions, the detection limits of this method for Pb was 0.053 μg mL-1, and the relative standard deviation (R.S.D %) was 4.27% (n =11, c = 0.5 μg mL-1). The proposed method has been successfully applied to determination of trace lead in environmental water samples with satisfactory results. This simple method shows a great potential for determination other trace metals in environmental samples.
