Abstract
Polysulfone (PSf) was functionalized with three different metal-ion ch elating ligands: 8-hydroxyquinoline, 1-(2-pyridylazo)-2-naphthol, and 4-(2-pyridylazo)-resorcinol. These chelating group-immobilized polysul fone polymers were evaluated for the chelation of trace metals from se awater samples. The chelating characteristics of PSf modified with 8-h ydroxyquinoline were superior to the others. In addition to the powder form, microfiltration membranes were cast, modified and evaluated for heavy metal chelation.
