Abstract
A simple and rapid method for spectrophotometric determination of pall adium from highly acidic and highly radioactive nuclear waste using al pha-benzoin oxime (ABO) as extractant and isobutyl methyl ketone (hexo ne) as diluent has been developed. The method can be employed over a w ide range of nitric acid concentrations and for palladium concentratio ns in the range of 1 . 10(-5)M to 4 . 10(-4)M in the organic phase. Th e molar absorptivity was found to be 4 . 10(3) 1 . mol-1 . cm-1. Influ ence of various heavy metal ions, fission products and corrosion produ cts was studied. The method was found to give a precision and accuracy better than 4% at 100 mug of palladium.
