Abstract
Official abstract text for this publication.
Methods for isolating Pb and/or Pb isotopes from various sources are provided. Compositions comprising Pb and/or Pb isotopes free of certain amounts of various contaminants are also provided.
First claim
Opening claim text (preview).
What is claimed is: 1. A method, comprising contacting a chelating resin that comprises iminodiacetic acid with a solution comprising Pb, and eluting the Pb bound to the chelating resin with a heated sodium hydroxide solution, wherein the heated sodium hydroxide solution is at a temperature suitable for the selective elution of Pb. 2. The method of claim 1 , wherein the temperature of the heated sodium hydroxide solution is about 85-95° C. 3. A method, comprising contacting a chelating resin that comprises iminodiacetic acid with a solution comprising Pb, and eluting the Pb bound to the chelating resin with heated sodium hydroxide solution, wherein the temperature of the sodium hydroxide is at about 90° C. 4. A method, comprising eluting Pb from a chelating resin using a sodium hydroxide solution at a temperature of about 85-95° C. or of about 85° C. or higher.
