摘要：3,6-dihydrothiazolo [5, 4-d] thiazole which supported on polyurethane was synthesized. The prepared compound was characterized by FTIR and 1 H NMR spectroscopy. The chelating properties towards various metal ions Pb 2+ , Mn 2+ , Cr 3+ , Co 3+ and Cd +3 was examined. The effects of concentration of metal ions, time of extraction and pH as well as the recovery of ions have been studied. The results showed that the high activity order of resin to extract the metal ions is Pb 2 > Cd +3 > Mn 2+ >Cr 3+ > Co 3+ .
