title: Conversion of 111In-oxine to 111In trichloride by acid hydrolysis.
abstract: The lipophilic complex 111In-oxine was converted back to 111InCl3 by acid hydrolysis with 0.1 N HCl. Greater than 99% of the starting material was converted to 111InCl3 with a purity of 99.6%. Unlabeled oxine was completely removed by chloroform extraction. Current experimental data suggest that 111In-oxine is unstable in weak acidic medium.
