Approaches toward synthesizing novel extractant systems: polymeric bifunctional extractants with synergistic possibilities
Journal Article

· Sep. Sci. Technol.; (United States)
The synthesis of a monoarylphosphinic acid diarylphosphine oxide extractant system supported on macroporous polystyrene beads is reported. The bifunctional resin was used in separate zinc and copper(II) ion extraction studies. Results with both metals show an excellent extent of extraction under low loading conditions and solution pH of 1-2; at equivalent metal:resin concentrations, the resin absorbs 50% of the metal in solution. Comparison with lower absorption values reported in the literature for similar systems suggests the possibility of a synergistic extraction due to cooperation between the acid and oxide moieties. 30 references.
