Iron/iron oxide nanoparticle sequestration of catalytic metal impurities from aqueous media and organic reaction products

A host of transition metal ions (Co2+, Cu2+, Ni2+, RuX+, RhX+, Pd2+, Ag+, and Pt4+) were sequestered from aqueous media upon exposure to FexOyFe nanoparticles. Concentrations were lowered from approximately 100 ppm to below 40 ppb. This technique was extended to the removal of catalytic ions from th...

Zusammenfassung:A host of transition metal ions (Co2+, Cu2+, Ni2+, RuX+, RhX+, Pd2+, Ag+, and Pt4+) were sequestered from aqueous media upon exposure to FexOyFe nanoparticles. Concentrations were lowered from approximately 100 ppm to below 40 ppb. This technique was extended to the removal of catalytic ions from the products of a "Click" cycloaddition and a Heck coupling in organic solvents. Residual metal concentrations in organic reaction products matched or exceeded pharmaceutical standards
