Popis:	Waste water containing heavy metal ions is being discharged from numerous industries and can cause several problems due to high toxicity and water solubility. It is crucial to treat metal containing water before discharging into the environment. Dendrimers are a new class of macromolecules. Due to their dense terminal functionality and internal cavities, they are perfect for water remediation by adsorption. In this paper, we have synthesized hydroxyl terminated triazine-based dendrimer generations by divergent method using piperazine, triazine trichloride and diethanolamine as starting materials. Full generation dendrimers G1(OH)8, G2(OH)32 and G3(OH)128 were terminated by 8, 32 and 128 hydroxyl groups, respectively. Structures of dendrimer generations were characterized by infrared spectroscopy (FT-IR), 1H NMR, 13C NMR, and electrospray ionization mass spectrometry. Hydroxyl terminated full dendrimers G1(OH)8, G2(OH)32 and G3(OH)128 were used as adsorbents in a series of experiments to study the ...
