摘要:

Citrazinic acid was tested with 34 cations in slightly acidic medium but U(VI) and Fe(III) only gave colored reactions. Fe(III) is masked with ascorbic acid thus the reagent can be used for the simultaneous spectrophotometric determination of U(VI) and Fe(III) in presence of the remaining tested cations.
