Abstract
Official abstract text for this publication.
Methods of purifying acidic metal solutions by removing at least a portion of alpha-particle emitting materials are provided. The purified metal solutions are useful in a variety of applications requiring low levels of alpha-particle emission.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for purifying a tin solution comprising: providing an acidic tin solution having an alpha-emitting material comprising one or more of 210 Pb, 211 Bi and 212 Bi; contacting the tin solution with an ion exchange resin for a period of time sufficient to remove at least a portion of the alpha-emitting material comprising one or more of 210 Pb, 211 Bi and 212 Bi; and separating the tin solution from the ion exchange resin to provide a purified tin s…
