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 gelatin used in this experiment was extracted from chrome shavings. And gelatin microspheres (GMs) were synthesized by emulsion cross-linking method with glutaraldehyde as crosslinker. The adsorption property of heavy metal ions on GMs was researched by taking Cu2+ for example. The absorption process was fitting for the Freundlich equation. The study of Freundlich adsorption isotherms and thermodynamics showed that when the adsorption dosage of Cu2+ were 0.10 ~ 0.13mmol·g-1 at 293 ~ 333 K, adsorption enthalpy ΔH were positive, adsorption free energy ΔG were negative and adsorption entropy ΔS were over zero. This results indicated that the adsorption was an endothermic, spontaneous and entropy increase process.
