Abstract
A radiometric method based on substoichiometric isotope dilution analy sis using 1,10-phenanthroline and a substoichiometric amount of eosin was developed for determining trace amounts of zinc. Evaluation of var ious metal ion interferences showed that as little as 0.2 mu g Zn coul d be determined in an aqueous-phase volume of 60 mL. The method has be en successfully applied to the determination of Zn in city waste incin eration ash, cadmium metal, Fourts-B tablets, Boro-plus ointment, and magnesium alloy samples.
