Abstract
The determination of thallium in unalloyed zinc by proton activation analysis, based on the 203Tl (p,3n) 201Pb reaction, is described. Lead-201 was radiochemically separated from the matrix activities (gallium, copper and zinc) by cation exchange, anodic deposition of lead (IV) oxide and precipitation as lead thionalide. Thallium (III) oxide was used as the standard. The method was applied to the BCR reference materials 321,322,323,324 and 325 Unalloyed Zinc. The detection limit is 17 ng g −1. The relative standard deviation obtainable is 5-1% in the 1-40 μg g −1 concentration range.
