A new low-cost polymeric adsorbents with polyamine chelating groups for efficient removal of heavy metal ions from water solutions

Two new low-cost polymeric adsorbents have been obtained in a simple reaction of diethylenetriamine (DETA) or pentaethylenehexamine (PEHA) with 1,3,5-tris(6-isocyanatohexyl)-1,3,5-triazinane-2,4,6-trione (HDI-IC). The reagents used for the synthesis are inexpensive and are produced yearly in high qu...
