Potential Heavy Metal Water Remediation Using 5-Formylfuran-2-Sulfonic Acid Thiosemicarbazone Chelating Resins

Strong anion exchange resins were separately loaded with three new 5-formylfuran-2-sulfonic acid thiosemicarbazone ligands and tested to determine if they could be utilized for heavy-metal water remediation. The ligands were tested for microbial activity using MIC tests, and were found to be inactiv...

Description
Summary:Strong anion exchange resins were separately loaded with three new 5-formylfuran-2-sulfonic acid thiosemicarbazone ligands and tested to determine if they could be utilized for heavy-metal water remediation. The ligands were tested for microbial activity using MIC tests, and were found to be inactive even at high concentrations. Resins used in the study were loaded with one percent by weight of each ligand, and then were exposed to Co-57, Ni-63, or Cd-109, using batch techniques at various environmental pH levels at different time intervals. The adsorption values of the metals to the resin beads were calculated as dry-weight distribution (Dw) values.
