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 modified eggshell membrane (modified-ESM) was prepared by esterification between thioglycolic acid (CH2SHCOOH) and oxygen-containing functional groups on eggshell membrane (ESM). A promising potential biosorbent, modified-ESM, was used for the removal of toxic cadmium (II) from aqueous solution. Aqueous of cadmium ions removing properties using by modified-ESM were studied through batch experiments. The results indicated that the modified ESM has greatly enhanced the adsorption capacity for Cd2+, the maximum capacity was increased more than 5-fold in comparison with the unmodified ESM, from 17.1 mg g-1 to 90.3 mg g-1. The optimum of pH value for Cd adsorption was in the range of 5-8, which the removing rate over 96%. The results obtained show that the novel modified eggshell membrane performed well the removal and recovery of cadmium from low concentration wastewaters.
