|a As the generation number of dendrimers increases, more organic branches and terminal groups are synthesized on the surface. However, this may not be actual situations in all generations of dendrimers. Different generations of magnetic cored dendrimer (MCD) terminalized with amine functional groups were compared as adsorbents for heavy metal ions in water. To determine the optimal generation number as adsorbent, the maximal adsorption of lead and cadmium on generation 1, 2, and 3 (G1, G2, and G3) MCDs. Higher generation MCD had more organic contents and possibly terminal groups on its structure. However, G2 MCD was the highest in adsorbing both lead and cadmium. An acid-base titration was performed to quantify the amine functional groups. The active amine sites on G2 are 4.35 times as much as that of G1 and 0.12 times as much as that of G3, which coincided with the adsorption experimental result. Incomplete dendritic structure formation due to steric hindrance caused G2 MCD to be the most efficient among the three generations of MCDs in this research
