Application of Ferritin Modified Eggshell Membrane in Heavy Metal Ion Uptake and Recovery

Article Preview

Abstract:

A ferritin mutant A1C with 24 free SH groups on its outer surface was prepared, which was successfully cross-linked to hen eggshell membrane outer layer (ESM-OL) by a disulfide linkage as characterized by SEM and TEM. Generally, this ferritin conjugated ESM-OL (Ft-ESM-OL) exhibited a significantly higher activity of heavy metal ion uptake as compared to ESM-OL alone under the same experimental conditions. For example, the adsorption capacity of Ft-ESM-OL for U6+ and Fe2+ were 21.16% and 18.4% higher than that of natural ESM-OL, respectively. On the other hand, the recovery capacity of Fe2+ by Ft-ESM-OL was 8.11 mg/g ESM, a value 67.9% higher than that of natural ESM-OL. Thus, this newly ferritin-modified ESM-OL greatly improved the adsorption and recovery efficiency of heavy metal ion as compared to ESM-OL alone.
