We present the research on the synthesis of a new series of DIFANEX chelating resins for uptake of transition metal ions. Thiosemicarbazone ligands were used to make chelating resins for metal adsorption from aqueous solutions. To create the ligands, 5-formylfuran-2-sulfonic acid was reacted with three different thiosemicarbazides and two semicarbazides to give a series of five compounds. The ligands synthesized were used to prepare chelating-ligand resins (DIFANEX) which were tested for metal ion uptake using a radiotracer technique with the 109Cd, 60Co, and 63Ni isotopes. The metal ion uptake was tested at pH 4, 6, and 8 at various exposure times to determine possible environmental usage for metal remediation.
