摘要：

The chelation behavior of the Mannich-type polymers, poly[8-hydroxyquinoline-5,7-(piperazine-N,N'-diyl-bismethylene)], polymer 1, and poly[8-hydroxyquinoline-5,7-(N,N'-dimethylethylenediamine-N,N'-diyl-bismethylene)], polymer 11, toward the trivalent lanthanide metal ions, La(III), Nd(III), Sm(III), and Gd(III) was studied by a static batch equilibration technique as a function of contact time, pH, and counter ion. The highest metal-ion uptake of these polymers was achieved at pH greater than or equal to 7.0 and by using perchlorate as the counter ion.
